   This function is meant to copy all the attributes from a  
   specified (dataset) --> path to another volume hear information.
   It recursively finds all the attributes (non-standard) and copies 
   them one by one. It comes in handy in cases where you create an image 
   from an existing image and do not wish to lose any information supplied with the minc header.

   attribute(s) and copies them to the new volume or MI_ERROR otherwise
 

milist_start edit

 NAME 
 
 milist_start - get list of attributes or groups starting at given path
 
 SYNOPSIS
 
 #include <minc2.h>

                    milisthandle_t          *handle)
 
                                                 
 DESCRIPTION
 
 This function begins listing the attributes or groups in the 
 given path.
 
 If the flags argument includes MILIST_RECURSE, then all of the 
 paths subgroups will be searched and their attributes or groups 
 will be listed as well.
 
 The path string should always end with a slash ("/") character.
 
 The returned handle is used to pass to milist_attr_next() for 
 attributes or milist_grp_next() for groups and 
 milist_finish() to actually perform the listing operation.
 
 RETURN VALUE
 
 milist_start returns MI_NOERROR if it successfully gets the
 attribute(s) or group(s) or MI_ERROR otherwise
 

milist_attr_next edit

 NAME 
 
 milist_attr_next - get the attributes at given path
 
 SYNOPSIS

                         int                     maxname)
 
 DESCRIPTION
 
 This function returns each of the attributes associated with the
 listing initiated by a call to milist_attr_start().  Each successive
 call of the milist_attr_next() function returns the next attribute's
 path and name in the corresponding string buffers.  
 
 When all possible attributes have been returned, the function returns
 an error.
 
 The maxpath and maxname parameters are used to set the maximum length of the
 two string buffers.
 
 If the listing operation is not recursive, the path parameter will always
 have length zero (the empty string).
 
 RETURN VALUE
 
 milist_attr_next returns MI_NOERROR if it successfully gets the
 attribute name or MI_ERROR otherwise

 DESCRIPTION
 
 This function returns each of the groups associated with the listing 
 initiated by a call to milist_start(). Each successive call to 
 milist_grp_next() returns the next group's path in the corresponding 
 string buffer.
 
 When all possible groups have been returned, the function returns an error.

         MI_TYPE_UNKNOWN  = -1     /* when the type is a  non_uniform record */
 
 } mitype_t;
 
 typedef struct {
         short real;
         short imag;
 } miscomplex_t;
 
 typedef struct {

 MI_NOERROR on success.

miget_space_name/miset_space_name edit

 NAME 
 
 miget_space_name, miset_space_name - get or set the space type name for
 a MINC volume
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int miget_space_name( mihandle_t volume, char **name );
 
 int miset_space_name( mihandle_t volume, const char *name );
 
 DESCRIPTION
 
 miget_space_name retrieves the "space" name of the given volume,
 returning a pointer to a string.  The memory allocated
 by this function should be released with a call to mifree_name().
 
 miset_space_name will set the space name of the volume.  The new name
 must be no greater than 128 characters in length, including the
 trailing zero byte.
 
 Space names are used to define the coordinate system of the volume.  Three
 standard values are defined by MINC:
 
 MI_NATIVE    "native____"
 MI_TALAIRACH "talairach_"
 MI_CALLOSAL  "callosal__"
 
 "Native" space specifies the coordinate system of a particular
 scanner.  Talairach and callosal are standard coordinate systems for
 brain images.
 
 If not explicitly set, the space will be type MI_NATIVE by default.
 
 RETURN VALUE
 
 miget_space_name returns the length of the name retrieved, including
 the terminating zero byte.  miset_space_name will return MI_NOERROR
 on success.  Both functions return MI_ERROR if an error occurs.

                                   mihandle_t            *volume)
                                 
 DESCRIPTION
 
 This method returns the volume handle associated with a given dimension.
 
 
 RETURN VALUE
 
 miget_volume_from_dimension returns MI_ERROR if the specified handle
 is not associated with the volume and MI_NOERROR otherwise.

micopy_dimension edit

 NAME
 
 micopy_dimension - create copy of the given dimension
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int micopy_dimension ( midimhandle_t       dim_ptr,
                        midimhandle_t       *new_dim_ptr)
 
 DESCRIPTION
 
 Creates a copy of the specified dimension and returns the handle to the copy
 
 RETURN VALUE
 
 micopy_dimension returns MI_NOERROR if it successfully copies all the 
 attributes of the provided dimension and MI_ERROR otherwise

micreate_dimension edit

 NAME
 
 micreate_dimension - define a new dimension in a MINC volume
 
 SYNOPSIS
 
 #include <minc2.h>
 
 
 int micreate_dimension ( const char     *name,
                          midimclass_t   class, midimattr_t      attr,
                          unsigned int  size, midimhandle_t     *new_dim_ptr);
 
 DESCRIPTION
 
 This function defines a dimension that can be used in the definition
 of a new MINC volume (see the create_volume function).  The name may
 be an arbitrary string of up to 128 alphanumeric characters. Any of
 the "standard" names retained from MINC 1.0 retain their default
 behaviors: MIxspace, MIyspace, and MIzspace default to spatial
 dimensions, and MItime default to be a time dimension.  MItfrequency
 is a temporal frequency axis, and MIxfrequency, MIyfrequency, and
 MIzfrequency are spatial frequency axes.  Any other name may be used.
 
 When initially defined, a regularly-sampled dimension will have a
 "start" value of zero, and a "separation" or "step" value of 1.0.  An
 irregular dimension will be initialized with all offsets equal to
 zero.
 
 The type midimclass_t is defined as follows:
 
 typedef enum { 
 MI_DIMCLASS_ANY         = 0,            /* Don't care (or unknown) */
 MI_DIMCLASS_SPATIAL     = 1,            /* Space */
 MI_DIMCLASS_TIME        = 2,            /* Time */
 MI_DIMCLASS_SFREQUENCY  = 3,            /* Spatial frequency */
 MI_DIMCLASS_TFREQUENCY  = 4,            /* Temporal frequency */
 MI_DIMCLASS_USER        = 5,            /* Arbitrary user-defined axis */
 MI_DIMCLASS_FLAT_RECORD = 6             /* Record as dimension */
 
 } midimclass_t;
 
 The type midimattr_t is a bit field of dimension attributes, defined as
 follows:
 
 typedef unsigned int midimattr_t; 
 #define MI_DIMATTR_ALL 0
 #define MI_DIMATTR_REGULARLY_SAMPLED 0x1
 #define MI_DIMATTR_NOT_REGULARLY_SAMPLED 0x2
 
 The "size" argument may range from 0 to 2^32, which should provide
 enough range to represent detail on the order of 10 Angstroms in
 typical medical imaging applications.
 
 If successful, the function will return a handle to the newly-defined
 dimension in the location specified by "new_dim_ptr".
 
 RETURN VALUE
 
 micreate_dimension returns MI_NOERROR on success, MI_ERROR on failure.

mifree_dimension_handle edit

 NAME

 with the given handle
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int mifree_dimension_handle ( midimhandle_t       dim_ptr)
 
 DESCRIPTION
 
 Deletes the dimension definition (i.e., dimension handle and dimension itself)
 only if the dimension is NOT associated with a volume.
 
 RETURN VALUE
 
 mifree_dimension_handle returns MI_NOERROR if it successfully deletes 
 a dimension or MI_ERROR otherwise.

miget_volume_dimensions edit

 NAME  
 
 miget_volume_dimensions - retrieve the list of dimensions defined in a MINC 
 volume, according to their class and attribute.
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int miget_volume_dimensions ( mihandle_t        volume, 
                               midimclass_t      class, 
                               midimattr_t       attr, 
                               miorder_t         order,
                               int               array_length,
                               midimhandle_t     dimensions[]);
                               
 
 DESCRIPTION
 
 This function is used to retrieve an array of dimension handles for a
 MINC volume.  It will place the handles of the first "array_length"
 dimensions into the "dimensions[]" array, returning only those dimension
 whose characteristics match the "class" and "attr" parameters. 
 The miorder_t is an enumerated type flag which determines whether the
 dimension order is determined by the file or by the apparent order set by 
 the user. This function will FAIL if the user has not set the apparent 
 dimension order by calling either of 
 miset_apparent_dimension_order() or miset_apparent_dimension_order_by_name()
 before calling this function with MI_DIMORDER_APPARENT flag
 
 
 The following example will return up to 3 spatial dimensions:
 
     int result;
     midimhandle_t dimensions[3];

 DESCRIPTION
 
 This method sets an apparent dimension order. The user can sort the
 dimensions in any desired order. If the user specifies fewer dimensions
 than the existing ones, then they are assumed to be added to the last.
 For example, given (z,y,x) for the file dimension order of (x,y,z,t) 
 will result in (t,z,y,x) and so on. 
 
 RETURN VALUE
 
 miset_apparent_dimension_order returns MI_NOERROR if it successfully
 sets the apparent dimension order or MI_ERROR otherwise

miget_dimension_class/miset_dimension_class edit

 NAME
 
 miget_dimension_class, miset_dimension_class - get or set the class of
 a MINC dimension.
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int miget_dimension_class ( midimhandle_t       dimension,
                             midimclass_t        *class );
 
 int miset_dimension_class ( midimhandle_t       dimension,
                             midimclass_t        class);
 
 DESCRIPTION
 
 The "class" of a MINC dimension defines the general type of a dimension, 
 whether it is a spatial dimension, a time dimension, or a frequency dimension
 as transformed from either space or time.  User-defined dimension are also
 permitted, with no default handling assumed. Finally, a record can be specified
 as a dimension.
 
 The definition of midimclass_t is as follows:
 
 typedef enum { 
 MI_DIMCLASS_ANY         = 0,            /* Don't care (or unknown) */
 MI_DIMCLASS_SPATIAL     = 1,            /* Space */
 MI_DIMCLASS_TIME        = 2,            /* Time */
 MI_DIMCLASS_SFREQUENCY  = 3,            /* Spatial frequency */
 MI_DIMCLASS_TFREQUENCY  = 4,            /* Temporal frequency */
 MI_DIMCLASS_USER        = 5,            /* Arbitrary user-defined axis */
 MI_DIMCLASS_FLAT_RECORD = 6             /* Record as dimension */
 
 } midimclass_t;
 
 
 While the MINC library does not enforce any particular semantics based
 upon dimension class, individual MINC programs may define default
 behaviors for certain classes of dimensions.
 
 RETURN VALUE
 
 Returns MI_NOERROR on success, or MI_ERROR on failure.

miget_dimension_cosines/miset_dimension_cosines edit

 NAME
 
 miget_dimension_cosines, miset_dimension_cosines - Get or set the dimension's
 cosine vector.
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int miget_dimension_cosines ( midimhandle_t dimension,
                               double        cosines[3]);
 
 int  miset_dimension_cosines ( midimhandle_t dimension,
                                const double  cosines[3]);
 
 DESCRIPTION
 
 Spatial dimension in MINC volumes may be associated with a vector of direction
 cosines which define the precise orientation of the axis relative to "true"
 x, y, or z coordinates.
 
 The direction cosine vector always consists of exactly three values
 which correspond to the x, y, and z directions, respectively.  This is
 true regardless of the ordering of dimensions in a specific volume or
 data object.
 
 Because of the direction cosines, it is possible for MINC volumes to
 define non-orthogonal dimensions.
 
 These functions fail if the dimension is not of the spatial class.
 
 RETURN VALUE
 
 Returns MI_NOERROR on success, or MI_ERROR on failure.

miget_dimension_description/miset_dimension_description edit

 NAME
 
 miget_dimension_description, miset_dimension_description - Get or set the dimension's description.
 
 SYNOPSIS

                                   char **comments_ptr);
 
 int miset_dimension_description ( midimhandle_t dimension,
                                   const char *comments);
 
 DESCRIPTION
 
 Get and Set the dimension description. Note that the spatial dimensions
 (xspace, yspace, zspace) are initialized according to minc1 description.
 All other dimensions will have an empty description unless set by the user.
 
 RETURN VALUE
 
 Returns MI_NOERROR on success, or MI_ERROR on failure.

miget_dimension_name/miset_dimension_name edit

 NAME
 
 miget_dimension_name, miset_dimension_name - get or set the identifier
 of a MINC dimension
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int miget_dimension_name ( midimhandle_t dimension, char **name_ptr );
 int miset_dimension_name ( midimhandle_t dimension, const char *name );
 
 DESCRIPTION
 
 miget_dimension_name retrieves the name of the given dimension, allocating
 the space needed.  The memory allocated by this function should be released
 with a call to mifree_name().
 
 miset_dimension_name will rename an existing dimension.  The new name
 must be no greater than 128 characters in length, including the
 trailing zero byte.
 
 RETURN VALUE
 
 miget_dimension_name returns the length of the name retrieved, including
 the terminating zero byte.  miset_dimension_name will return MI_NOERROR
 on success.  Both functions return MI_ERROR if an error occurs.

miget_dimension_offsets/miset_dimension_offsets edit

 NAME
 
 miget_dimension_offsets, miset_dimension_offsets - get or set the absolute
 world coordinates of points along a MINC dimension
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int miget_dimension_offsets ( midimhandle_t     dimension, 
                               unsigned long     array_length, 
                               unsigned long     start_position,
                               double            offsets[]);
 
 int miset_dimension_offsets ( midimhandle_t     dimension, 
                               unsigned long     array_length, 
                               unsigned long     start_position,
                               const double      offsets[]);
 
 DESCRIPTION
 
 These functions get or set the dimension offsets, that is, the
 absolute world coordinates of each sampled point along the dimension.
 
 The caller may retrieve up to "array_length" values, starting at the
 integer index "start_position".  Thus an arbitrary contiguous subset
 of the dimension's offsets may be retrieved or stored.  An error is
 returned if the "start_position" exceeds the total size of the
 dimension.  If the value of "start_position" is legal, but the sum of
 "start_position" and "array_length" exceeds the size of the dimension,
 the function will get or set offsets up to the size of the dimension.
 Any extra positions in the offsets[] array will be ignored.
 
 It is explicitly legal to call this function for a regularly sampled
 dimension.  The result will be a list of values calculated from the
 "start" and "separation" values of the dimension.  However, it is 
 not possible to set offsets on a regularly sampled dimension.
 
 RETURN VALUE
 
 Returns the number of offset values read or written , or MI_ERROR if
 an error is detected.

miget_dimension_sampling_flag/miset_dimension_sampling_flag edit

 NAME
 
 miget_dimension_sampling_flag, miset_dimension_sampling_flag - get or set
 the sampling flag for a MINC dimension
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int miget_dimension_sampling_flag ( midimhandle_t       dimension,
                                     miboolean_t         *sampling_flag);
 
 int miset_dimension_sampling_flag ( midimhandle_t       dimension,
                                     miboolean_t         sampling_flag);
 
 DESCRIPTION
 
 The miget_dimension_sampling flag function retrieves the value
 of the "sampling" flag for a given MINC dimension.  This flag
 is false (zero) if the dimension is sampled at regular
 intervals, and true (non-zero) if the dimension is sampled irregularly.
 
 If a dimension has regular sampling, the miget_dimension_step
 function may be used to retrieve the sampling interval, and the
 miget_dimension_start function may be used to retrieve the origin
 value along the axis.
 
 If a dimension has irregular sampling, the miget_dimension_offsets
 function may be used to retrieve the positions of each sample along
 that axis.
 
 RETURN VALUE
 
 These functions returns MI_NOERROR on success, or MI_ERROR if an 
 error is detected (for example, if a parameter is invalid).

miget_dimension_separation/miset_dimension_separation edit

 NAME
 
 miget_dimension_separation, miset_dimension_separation - set/get the 
 sampling interval for a single dimension
 
 SYNOPSIS

                                  double                 *separation_ptr );
 
 int miset_dimension_separation ( midimhandle_t          dimension,
                                  double                 separation );
 
 DESCRIPTION
 
 Gets or sets the constant sampling interval defined on a regularly-sampled
 dimension.  While it is legal to call these functions for an irregularly-
 sampled dimension, the values will be ignored. The mivoxel_order_t is an 
 enumerated type which is defined as follows
 
 typedef enum {
         MI_ORDER_FILE   = 0,
         MI_ORDER_APPARENT  = 1
 } mivoxel_order_t;
 
 This flag specifies whether the voxel order is original from file or
 is an apparent one which can be the default (i.e., the same as the 
 original file) or the order that is specified by the user.
 
 If not explicitly set, the separation will have a default value of one.
 
 RETURN VALUE
 
 Returns MI_NOERROR on success, or MI_ERROR on failure.

                                   const double          separations[] );
 
 DESCRIPTION
 
 These functions get or set the scalar separation (sampling interval)
 associated with each of the dimensions in the input "dimensions[]"
 array.  The "array_length" parameter specifies the size of both the
 input and output arrays. While it is legal to call these functions for

                            unsigned int         size );
 
 DESCRIPTION
 
 These functions get or set the size (or length) of a MINC 2 dimension
 object used in creating a new volume.  The size of a dimension
 associated with an existing volume cannot be changed.  One can, however,
 make a copy of an existing dimension and set the size of the copy.

 DESCRIPTION
 
 These functions get or set the dimension width, that is, the
 full-width half-maximum values of each sampled point along the
 dimension.  
 
 These functions are used to set a constant width for regularly-sampled
 dimensions.
 
 If not explicitly set, the width will be assumed to be equal to the
 dimension's step size.

                              const double       widths[]);
 
 DESCRIPTION
 
 These functions get or set the dimension widths, that is, the
 full-width half-maximum values of each sampled point along the
 dimension.
 
 The caller may retrieve up to "array_length" values, starting at the
 integer index "start_position".  Thus an arbitrary contiguous subset
 of the dimension's widths may be retrieved or stored.  An error is
 returned if the "start_position" exceeds the total size of the
 dimension.  If the value of "start_position" is legal, but the sum of
 "start_position" and "array_length" exceeds the size of the dimension,
 the function will get or set widths up to the size of the dimension.
 Any extra positions in the widths[] array will be ignored.
 
 It is explicitly legal to call this function for a regularly sampled
 dimension.  The result will be a list of constant width values.
 However, it is not possible to set widths on a regularly sampled
 dimension.
 
 RETURN VALUE
 
 Returns the number of offset values read or written , or MI_ERROR if
 an error is detected.

 This method sets the hyperslab with the specified icv.
 It is important to mention that if the apparent dimension order of 
 the volume has been set (miset_apparent_dimension_order or 
 miset_apparent_dimension_order_by_name) and is different from 
 the dimension order of the file, then the buffer will
 be re-ordered in-place before the hyperslab is written.

 The void pointer would get casted to the appropriate type once it is used. 
 The data_type argument will be used to ensure type compatibility with the 
 hyperslab data type. 
 It is important to mention that if the apparent dimension order of 
 the volume has been set (miset_apparent_dimension_order or 
 miset_apparent_dimension_order_by_name) and is different from 
 the dimension order of the file, then the buffer will
 be re-ordered in-place before the hyperslab is written.

%=IMAGE CONVERSION VARIABLE FUNCTIONS (4)= %==miicv_volume_attach== %

 %NAME
 
 %miicv_volume_attach - attach a MINC ICV object to a MINC 2.0 volume.
 
 %SYNOPSIS
 
 %#include <minc2.h>
 
 %int miicv_volume_attach ( int           icv, 
                          % mihandle_t    volume);
 
 %DESCRIPTION
 
 %This function attaches a MINC image conversion variable (ICV) object
 %to a MINC 2.0 volume.
 
 %Given the flexibility of the MINC format, there are many different
 %possible choices available for details such as dimension order, data
 %type, and data range. Accounting for all of the possible combinations
 %of these items could make MINC programming too complex or unwieldy in
 %many situations.
 
 %MINC ICV objects are a solution to this problem.  They are essentially
 %a specification of the properties that the programmer would like the
 %data to have. The ICV is responsible for making any necessary
 %conversions, hiding the details of the actual data format from the
 %programmer.
 
 %A program may allocate any number of ICV objects and may configure and
 %attach them independently, allowing the program to have several
 %different views of the volume's data at the same time.
 
 %Note that ICV properties cannot be modified while a variable is
 %attached to the ICV. If a file and variable are already attached to
 %the ICV, they will be automatically detached before the new variable
 %is attached.
 
 %NOTE
 
 %This interface is being extended to allow use with the new MINC 2.0
 %interface, however, the existing ICV interface will be retained as
 %well.
 
 %RETURN VALUE
 
 %MI_NOERROR on success, or MI_ERROR on failure.

SLICE/VOLUME SCALE FUNCTIONS (14) edit

miget_slice_max edit

 NAME 
 
 miget_slice_max - get maximum real value of all the slice
 
 SYNOPSIS
 
 #include <minc2.h>
 
 int miget_slice_max ( mihandle_t        volume,
                       unsigned long     start_positions[],

                       double            *slice_max)
                        
 NOTE
 
 All of the slice scale (i.e., one scale per slice) functions take an array
 of long integer coordinates to specify the slice in particular and the order 
 of the coordinates is always set to FILE ORDER of the dimensions (i.e. not the
 apparent order). The number of coordinates to specify is the first (n-2) 
 dimensions except in the case of a uniform record which is also flattened
 (i.e., flatten_flag=1) that is the first (n-3) dimensions.                                
 
 
 DESCRIPTION
 
 This method returns the slice_max with the minimum real value of
 the corresponding slice. Note that this function is not defined for
 floating point data type nor it works if the volume is globally scaled.
 
 RETURN VALUE
 
 miget_slice_max returns MI_NOERROR if it successfully returns the slice_max
 or MI_ERROR otherwise
