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.

Dear Experts,

It might my naive question about 3dAutoTcorrelate.
Please let me make clear my question.

I think a method to remove nuisance variables (e.g., signal from white matter, csf, head motion so on) from time series may be the usage of 3dDeconvolve before performing correlation analysis. Am I right?

I'd like to remove nuisance variables in, not before, correlation analysis. (similar to what 1dGC.R or 3dGC.R can do) It seems a option of 3dTcorrelate, -ort, could do.
Does 3dAutoTcorrelate have any option to deal them as nuisance variable (aka partial correlation)?

thanks,

Jeong
