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

When attempting to using 1deval to multiply my neuronal activity file by a timing series(for the stimulus) file, I keep getting -0 as the result. There must be a simple command i'm doing incorrectly. I've attempted to use my combination of 0's and 1's in one large row, and also one large column, no matter how I create my timing file, I always get one -0 value as the result.

example code: 1deval -a "Neuronal activity file".1D -b "time series".1D -expr 'a*b" > Result.1D

why am I always getting -0 as the result?
