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

Hi Stef,

Sorry for being so slow to reply to this.

Yes, you can separate the final errts dataset into two pieces using 3dTcat. It should not be necessary to run afni_proc.py once for each run (depending on your answer to the following question).

Did the subjects leave the scanner between the two runs? If not, this seems okay. If they did, it would be better to allow for more flexibility in aligning the 2 runs.

To be sure, do you plan to compute correlations on each run separately? Or do you plan to correlate run 1 with run 2, say? The latter might be problematic due to (different) censoring between the runs. Correlating one run at a time should be reasonable.
