Tools for NIfTI and ANALYZE image

1. Thanks to the feedback and contribution of Chris McNorgan from Western University, the rri_orient.m now have optional parameter for orientation vector.
2. New program pad_nii.m is available together with clip_nii.m. See example in FAQ.pdf.

Since voxel size can be less than 0, I will change the default voxel_size in reslice_nii.m from rounded minimum voxel_size in original NIfTI header to absolute minimum voxel_size in original NIfTI header. This fixed reslice_nii bug.

Added some new features and fixed some bugs. For more detail, please visit:

Thanks to the feedback of Matthew Bickell from University of Cape Town, a bug is fixed when edit voxel in millimeter unit.

"make_nii.m" is now able to automatically detect both single and double complex data type.

Fixed a bug for yesterday's release

You can now create RGB NIfTI / ANALYZE file structure using make_nii / make_ana program.

New program "load_untouch_header_only.m" and "save_untouch_slice.m" is provided. Check http://www.rotman-baycrest.on.ca/~jimmy/NIFTI for more details.

New feature is added in "view_nii" program to let you edit voxel values or set landmarks. Also thanks to the code from Roman, which speed up "load_untouch_nii_img" program when the slices are not loaded at once.

1. Fixed an overlay problem in view_nii.m, so the color of min/max is now showing properly.
2. Included an overlay example in http://www.rotman-baycrest.on.ca/~jimmy/NIfTI/FAQ.htm and http://www.rotman-baycrest.on.ca/~jimmy/NIfTI/examples.txt.

Thanks to the feedback of Roman Fleysher from Yeshiva University, I fixed a bug when loading a quaternion form NIfTI data.

Thanks to Rembrandt from Radboud University Nijmegen (Netherlands), I made 2 small changes to handle the exceptions.

Fixed a bug in "collapse_nii_scan" to collapse Analyze format data.

1. "load_untouch_nii" now supports loading specific slices of NIfTI or Analyze format.
2. MATLAB ask me to remove any "under GNU license" phrase in any file.

"load_untouch_nii" now supports loading specific slices of NIfTI or Analyze format.

While an N-Dimensional matrix can be saved into a NIfTI file using "make_nii / save_nii" command pair, a 3D matrix can also be saved into an ANALYZE file using "make_ana / save_untouch_nii" in order to be compatible with some ANALYZE only programs.

Fixed several bugs, and posted informative table:

Just receive warning from MATLAB: "If I do not license my code with BSD, my code will be removed."

Thanks to the feedback of Kate Fissell from University of Pittsburgh, transformation matrix M will no longer be saved by save_untouch_nii.m.

1. Thanks to the feedback of Bryce Wilkins from USC, a typo in one of my message display is fixed.

2. Thanks to the suggestion of Ashish Raj from Cornell, 'expand_nii_scan.m' is modified and 'collapse_nii_scan.m' is added.

Default data type for 'make_nii.m' now follows the data type of 'img' matrix, instead of float32.

Fixed a bug in fliplr.m when reading files.

update didn't show up

1. Properly handle fread/'*char' problem with foreign characters in MATLAB 7 and above; 2. Reordered input parameters for 'reslice_nii.m' program;

Extended Load / Save / Make programs to N-Dimension, where N can be from 3 to 7 for NIfTI data and from 3 to 4 for ANALYZE data.
