When you run selxavg3-sess, add the -svres flag. This will save the residuals (ie, the time series without the nuisance variables)

External Email - Use Caution

Hi list,

I  would extract the rs-fMRI time-series from spitted components of Yeo's 7 Network Atlas (fsaverage5).

To this aim, I'm planning to convert the "fmcpr.odd.sm0.fsaverage.lh.nii.gz" (obtained by preproc-sess) on fsaverage5.

However, the fmcpr.odd.sm0.fsaverage.lh.nii.gz should still include some nuisance variables (CSF, the white matter, motion, first 4 time points).

To address this issue, is it corrected to apply the command lines reported below?

mkanalysis-sess -analysis fc.noseed.surf.lh -surface fsaverage lh -fwhm 0 -notask -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 -polyfit 5 -nskip 4 -mcextreg -fsd rest -TR 1.67 -per-run -hpf 0.01 -lpf 0.1 -nowhiten

mkanalysis-sess -analysis fc.noseed.surf.rh -surface fsaverage rh -fwhm 0 -notask -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 -polyfit 5 -nskip 4 -mcextreg -fsd rest -TR 1.67 -per-run -hpf 0.01 -lpf 0.1 -nowhiten

selxavg3-sess -s subj_folder_name -a fc.noseed.surf.lh -overwrite -no-con-ok

selxavg3-sess -s subj_folder_name -a fc.noseed.surf.rh -overwrite -no-con-ok

Thanks

Stefano
