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

Hey Rick -

Interesting. Any idea why omitting the bash looping construct, and just doing a single file, ie:

3dhistog whatever.nii | head -2 | tail -1

works? Is it just a race condition of some kind? I had assumed that stdout was not passed through the pipe until it was explicitly closed by the main process, so this is a definite learning moment. Thanks.
