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,

hello
I am new to afni and after running my first level models I am seeing the x axis is reversed (which is not that unusual) however I am also seeing the y axis is reversed. for example I am showing the left caudate at -16 -14 12 instead of 16 14 12 (it is the y axis reversed that has me most concerned)
is there a way I can correct for these reversals or at least correct for the y axis?

I do not understand why some subjects are not affected and others are. I am using the uber_subject.py gui to create the preprocessing scripts.
here is the script line where t
