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 Andrea,

In 3dcalc, the output datum is set by the first input, which
might be your mask. It's a subtle point to be aware of, if
that is what is causing you trouble. The mask is probably
unsigned bytes (small, non-negative integers), so that is what
the result would be.

Try running 3dcalc with the 3dmerge result as dataset '-a'
and the mask as dataset '-b'.

Or you could add the -datum option explicitly.

Please let me know whether that resolves the problem.

- rick
