you did not specify to include any motion correction regressors in the design. If that is what you want, then include -mcextreg

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 regressorsin 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.
According to *MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be* https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastTutorialV6.0/FsFastPreProc#M... https://secure-web.cisco.com/10LyHLSQ2Psfux7V-2TqU0TpTUpRE9gROQ8dm_KryluL_QNU55nhxXetOytBet_fQTG2A2PoLAke5cI9GoJ_eOzKwcQtM7JYw9WYkhhQtt4s_DvZSfuBoKyguaDrK0mk0JuETegFDP3ZyvD9qyw4cHTRZQb4vlDoArkNwd9vCCghIRn9t4xKTpeh9V8rLHllL_HSPRV5m0aF_axLuq8MDNrWo5dzq5hejqIK9sN2xGbSggauWRBsUhLpwYiivhVBn7KdQOMfU5Fu6_mxwrCIiNvR4h-Ppkv4hJ0XwVF4Yl9PZKclgLeYyDKzb_0D9qDTnFRh9CGp5eFa_0qD3zHhSSA/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FFsFastTutorialV6.0%2FFsFastPreProc%23MotionCorrection.28MC.29, motion correction parameters are stored in mcprextreg. Since there are 6 columns, I guess they are 3 translations and 3 rotations. On the other hand, none of them are in mcAll, X.mat. What are the 18 motion correction parameters in X.mat? and which motion correction parameters are used as nuisance regressors in FSFAST?
Thanks in advance.
