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 Jayna,

Daniel suggested that you might just want a union mask, and
re-reading your first post supports that.

For a union mask you can either run 3dcalc on the previous
output and use 'step(a)', or you can re-run the first command,
applying an 'or' or perhaps 'step' to the whole expression. E.g.

expr 'step(step(a-4.2)+2*step(b-2.9)+4*step(c-3.1))'
