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

Dear Afni experts:

I use 3dAllineate to register
imgA to imgB and get the regImg1 and reg1.aff12.1D
then
regImg1 to imgC and get regImg2 and reg2.aff12.1D

Now I would like to concatenate the transformation matrix using cat_matvec.
Should the order of the input matrix be:
reg1.aff12.1D reg2.aff12.1D
or
reg2.aff12.1D reg1.aff12.1D

Thanks in advance !!
