The simple answer is yes with
mri_glmfit --y func.nii.gz --mask yourbrainmask.mgz --osgm --pca --o glm
then look in the pca folder
However, this will only have the mean removed. If you want fancier detrending, you'll have to work a bit harder.

Dear list,

is possible to do a whole-brain, voxel-wise PCA analysis by FS-FAST?

Thanks

Stefano
