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 Rick,

I was originally using dmBLOCK, but switched to SPMG2 to account for the temporal derivative.

You are correct that the previous thread was using AM2. I missed that the first time. So will the code below give me duration modulated coefficients for both the regressor and its temporal derivative, if I also switch the stim time files to the stimulus onset:RT format (instead of stimulus onset*RT)?

- stim_times_AM2 5 ${subj}.Emo_Angry_Standard_ALL.1D 'SPMG2' \

I haven't been specifying a basis function. Should I be setting it to 1?

Thanks,
Phil
