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.
> if were to center the modulation parameter such that the maximum reaction time has a peak of 1, for each subject
I'm not so sure why you prefer to use the maximum reaction time as your benchmark for brain response interpretation. Also, you need to take into consideration the group analysis step: do you want to keep the same or different reaction time benchmark across subjects (which may have consequence at the group level)?
