AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Output:
RSP 0.453125 -0.453125 -0.453125 2097152 -28.773438 28.773438 28.773438 ORIG NIFTI
RSP 0.453125 -0.453125 -0.453125 2097152 -28.773439 28.773439 28.773439 ORIG BRIK

FOV: 58^3 mm^3
Matrix: 128^3
The real position should be 28.7734375. If rounded, it should be 28.773438, not 28.773439. Something not right about the BRIk converted by to3d.

Here is the command I used to convert NIFTI and BRIK
to3d -spgr -xFOV 29R-L -yFOV 29S-I -zFOV 29P-A -nofloatscan -prefix NIFT.nii.gz 3D:0:0:128:128:128:XX/XXX
to3d -spgr -xFOV 29R-L -yFOV 29S-I -zFOV 29P-A -nofloatscan -prefix BRIK 3D:0:0:128:128:128:XX/XXX
