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.
What do you mean by 'second order' GLT contrast? Was baseline modeled explicitly as a separate regressor in your model? Usually it's modeled with polynomials in 3dDeconvolve.
If you just want the beta contrast between RFacevB and RScrambledvB to feed into 3dRegAna, 3dcalc would be good enough. If you meant to be the data for donating/uploading, don't worry about it, and I will take care of the details.
