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

For many purposes, you can also create one-time use datasets directly on the command line. For example,

3dmaskave -mask '3dcalc( -a mask9+orig -expr step(equals(a,7)+equals(a,8)) )' fred+orig

would create the mask from Rick's example in memory, and then use it, then throw it away (no file left on disk). This trick can be useful in scripts, once you understand what you are doing.

See the section "CALCULATED DATASETS" in the output of afni -help
