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

I see that 3dDeconvolve is an OLSQ regression and 3dREMLfit is a GLSQ. I was under the assumption that 3dDeconvolve handled autocorrelation of the time series since this seems to be important in fMRI data. Is this true, or is 3dREMLfit the only program that does so? If this 3dREMLfit is the only program, then in what instances would one use 3dDeconvolve? Shouldn't all fMRI data be handled with taking autocorrelation into account?

Best,

Andrew
