/* ----------------------------- MNI Header ----------------------------------- @NAME : mincreshape @INPUT : argc, argv - command line arguments @OUTPUT : (none) @RETURNS : error status @DESCRIPTION: Program to allow reshaping of minc lattices: selecting a a subrange (or superrange) of dimension indices, eliminating dimensions, or re-ordering axes. As well, all icv conversions are made accessible on the command line. @METHOD : @GLOBALS : @CALLS : @CREATED : March 10, 1994 (Peter Neelin) @MODIFIED : * $Log: mincreshape.c,v $ * Revision 6.14 2008-01-17 02:33:02 rotor * * removed all rcsids * * removed a bunch of ^L's that somehow crept in * * removed old (and outdated) BUGS file * * Revision 6.13 2008/01/13 09:38:54 stever * Avoid compiler warnings about functions and variables that are defined * but not used. Remove some such functions and variables, * conditionalize some, and move static declarations out of header files * into C files. * * Revision 6.12 2008/01/12 19:08:15 stever * Add __attribute__ ((unused)) to all rcsid variables. * * Revision 6.11 2005/08/26 21:07:18 bert * Use #if rather than #ifdef with MINC2 symbol, and be sure to include config.h whereever MINC2 is used * * Revision 6.10 2004/11/01 22:38:39 bert * Eliminate all references to minc_def.h * * Revision 6.9 2004/04/27 15:30:02 bert * Add -2 flag * * Revision 6.8 2001/11/13 14:16:50 neelin * Get correct valid range for conversion from int to float types * * Revision 6.7 2001/09/18 15:32:53 neelin * Create image variable last to allow big images and to fix compatibility * problems with 2.3 and 3.x. * * Revision 6.6 2001/08/16 16:41:36 neelin * Added library functions to handle reading of datatype, sign and valid range, * plus writing of valid range and setting of default ranges. These functions * properly handle differences between valid_range type and image type. Such * difference can cause valid data to appear as invalid when double to float * conversion causes rounding in the wrong direction (out of range). * Modified voxel_loop, volume_io and programs to use these functions. * * Revision 6.5 2001/04/24 13:38:45 neelin * Replaced NC_NAT with MI_ORIGINAL_TYPE. * * Revision 6.4 2001/04/17 18:40:24 neelin * Modifications to work with NetCDF 3.x * In particular, changed NC_LONG to NC_INT (and corresponding longs to ints). * Changed NC_UNSPECIFIED to NC_NAT. * A few fixes to the configure script. * * Revision 6.3 1999/10/19 14:45:29 neelin * Fixed Log subsitutions for CVS * * Revision 6.2 1998/08/19 13:57:23 neelin * Fixed argument parsing to detect errors such as octal numbers * containing illegal digits (08) and extraneous characters on the end of * arguments. * * Revision 6.0 1997/09/12 13:24:12 neelin * Release of minc version 0.6 * * Revision 5.0 1997/08/21 13:25:10 neelin * Release of minc version 0.5 * * Revision 4.0 1997/05/07 20:01:44 neelin * Release of minc version 0.4 * * Revision 3.0 1995/05/15 19:32:36 neelin * Release of minc version 0.3 * * Revision 1.6 1995/02/09 14:08:24 neelin * Mods to make irix 5 lint happy. * * Revision 1.5 1995/02/08 19:31:47 neelin * Moved ARGSUSED statements for irix 5 lint. * * Revision 1.4 1994/11/23 11:47:05 neelin * Handle image-min/max properly when using icv for normalization. * * Revision 1.3 94/11/22 08:46:09 neelin * Fixed handling of normalization for number of image dimensions > 2. * Added appropriate default values of image-max and image-min. * * Revision 1.2 94/11/03 08:48:20 neelin * Allow chunk_count to have sizes less than full block size. * * Revision 1.1 94/11/02 16:21:24 neelin * Initial revision * @COPYRIGHT : Copyright 1993 Peter Neelin, McConnell Brain Imaging Centre, Montreal Neurological Institute, McGill University.
