Dear Douglas N. Greve,

My experiment design is block design with 2 conditions.

Here is the mkanalysis command line: mkanalysis-sess -fsd main -stc siemens \ -surface fsaverage lh -fwhm 0 -event-related -paradigm GLonset.par \ -nconditions 2 -spmhrf 0 -TR 2 -refeventdur 48 -nskip 0 -polyfit 3 \ -analysis GLanalysis01.lh -per-run -force

In addition, I attached the paradigm file, mcprextreg, and X.mat.

I want to know motion correction parameters used as nuisance regressors in FSFAST analysis. I appreciate your help.

Kind regards, Andy (Junghyun) Kim

These are not the basic translations and rotations, rather: mcprextreg - text file of the motion correction parameters assembled into an orthogonalized matrix that can be used as nuisance regressors

I don't know what your design is, please send your mkanalysis command lie

Dear FreeSurfer Developer,

Hi. Thanks to FreeSurfer, I could perform surface-based activation analysis with FSFAST. Now I want to do surface-based functional connectivity analysis. For the sake of consistency, I want to use the same nuisance regressors as used in FSFAST. Unfortunately I'm stuck in motion correction parameters.

Dear Douglas N. Greve,

Thank you. I followed your advice and re-ran the codes with -mcextreg. Now there are 3 more columns in X.mat for each run. I assume those 3 additional columns are motion correction parameters.

But what are they? Where do they come from? I couldn't find the same numbers in the mcprextreg files. I'm sorry to bother you, but I don't want to use data that I totally don't have idea. Please help. Thank you.

Dear Douglas N. Greve,

But the 3 additional columns in X.mat file (which is result of -mcextreg option in mkanalysis-sess command) are not the first 3 columns of mcprextreg file. They are totally different numbers. You are saying they (3 additional columns in X.mat file and the first 3 columns of mcprextreg file) should be the same, right? Or am I misunderstanding what you're saying?
