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

Hello,

No, -ONELINE does not imply -I.

The "3dvolreg -1Dmatrix_save" output is already in the direction needed, and does not need to be inverted in that case. See a more complete proc script for an additional example, such as AFNI_data6/FT_analysis/s15.proc.FT.uber.

The cat_matvec command there as well does not invert the 3dvolreg matrix (that last mat.r$run.vr.aff12.1D input), while it does invert the other ones.

The "3dvolreg -help" output does not say it needs -I, it says that if you do want to invert it, use "cat_matvec -I".

Does that seem reasonable?

Does "-ONELINE" also apply "-I" in cat_matvec ?
