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

Hi,
We use align_epi_anat.py to align the EPI data to anat data. The original EPI data is
R-to-L extent: -119.125 [R] -to- 117.875 [L] -step- 3.000 mm [ 80 voxels]
A-to-P extent: -130.462 [A] -to- 106.538 [P] -step- 3.000 mm [ 80 voxels]
I-to-S extent: -48.717 -to- 63.483 [S] -step- 3.300 mm [ 35 voxels]
After alignment, the EPI data is
R-to-L extent: -120.803 [R] -to- 128.197 [L] -step- 3.000 mm [ 84 voxels]
A-to-P extent: -136.396 [A] -to- 109.604 [P] -step- 3.000 mm [ 83 voxels]
I-to-S extent: -116.057 -to- 126.943 [S] -step- 3.000 mm [ 82 voxels]
The voxels number increased a lot, I think it is due to the extent of the anat data. Is there anyway, align the EPI data to anat, but keep the extent as original EPI data.
