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

How did you fractionalize the mask from +tlrc coordinates to +orig coordinates - by using the "-warp" option of 3dfractionize? Did you also use the "-preserve" option? Also, you might need to use the "-clip" option, otherwise voxels in the +orig dataset that only very slightly overlap the +tlrc ROI will become part of the ROI, which will cause the ROI to expand.

You should look at the ROI in +tlrc and +orig space to see what the geometrical or numerical cause of the problem is.
