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

Are you saying that you want to use skin conductance as a regression variable? That is, to try to account for variability in your fMRI time series that may be due to changes in skin conductance? If so, the skin conductance data would enter your analysis as a .1D file and be treated as a stimulus by incrementing you -num_stimts entry and adding an additional -stim_file entry.

If your temporal resolution is different than your fMRI data (and it appears that it is) you will have to resample your conductance data so that it has the same sample rate as your fMRI data.
