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

My next suggestion requires you to update your AFNI binaries, sometime on Friday (12 Feb 2016).

I added two options to 3dGroupInCorr:

-read makes the program read the data into memory, rather than memory map it

-ztest makes the program test the data (no matter how it was input) to see if it is all zero; this happens before the computations start, and a message is printed like
++ Running -ztest now
+ total of 0 datasets tested as all zero


So update your copy of AFNI, then run 3dGroupInCorr with the '-ztest' option to see if it detects any problems with the data.
