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

Qwarp registration to the TT_N27+tlrc brain should be done by blurring both the base (TT_N27) and the source datasets. The auto_warp.py script doesn't allow for this, apparently. You might get better results with a modified 3dQwarp command, but that won't fit into the afni_proc.py schema at this point in time.

Rick is out for the next 2 weeks, and changes to afni_proc.py will have to wait until he returns. Sorry.

If you want to try a modified 3dQwarp command, you can use the 3dinfo command on the output to see the command that produced the "droopy" file, and then re-run 3dQwarp with some extra options, such as

-blur 3 3 -workhard:0:1

to see if this helps cure the problem.
