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

To get everything (positive or negative) in one color, you would just add the abs (absolute value) function to your 3dcalc expression as in

3dcalc -a 'ANOVA_N24+tlrc[11]' -expr 'step(abs(a)-4.76)' -prefix words_vs_fix_00001

I believe Bob was talking about using the threshold slider with the Pos? button not selected.
