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

The multimask is based on the TT_Daemon using Brodmann areas. I tried to not have them touch, yet, this multimask if giving trouble:
3dcalc -a ba19_left+tlrc -b acc_left+tlrc -c parah_left+tlrc -expr 'step(a)+2*step(b)+3*step(c)' -prefix LeftMultiRegion_mask3

After fractionization I receive the notice:
Found 4 distinct nonzero values

And when I use it to measure my data I get 4 means columns.
Do I need to take the parahippocampus out and put it in a different mask?

multimask gives 4 means though only 3 distinct areas tested?
