Hello FreeSurfers,

I have an existing pipeline that computes the residualized time series after removing any linear trends using mri_glmfit:

mri_glmfit --y ${source_dir}/${r}/${filepat}.${surf}.${hemi}.nii.gz \
                               --glmdir ${source_dir}/${r}/${hemi}.detrend \
                               --qa --save-yhat --eres-save \
                               --surf ${SURFTOUSE} ${hemi}

This saves the detrended eres.mgh data in *h.detrend/

I would like to additionally include motion correction values as regressors in this step, but I am not completely clear how to do this.

My best guess is that this will entail a fixed effects analysis using the values in mcprextreg, but I cannot find any examples of this in the mailing list archives nor on the wiki, so any help would be greatly appreciated!

Thanks,

Chris
