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:
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 Paul,
yes, this is exactly what I am trying to do (the "center of mass" part was also part of my process
).
I am working here with PET FDG dataset on rats, that I believe are in sphinx position (that would make a lot of sense).
However, I am not sure I understand the purpose of the command
When I apply it (as advised), and then
it seems that the good orientation for 3drefit is: LIP and not LSP anymore.
In this case, L and Right are not changed.
This is where it gets tricky for me:
I don't understand the purpose of:
and so, why does applying it, change I to S in 3drefit when compared to my original dataset? and so LR...
Are there any issues applying directly the command 3drefit as I did previously?

thank you!
