Indeed, the GUI version does if you ask it to.

You might try just running melodic on your data as-is first and see if you get
anything that looks good. Otherwise, if you search the mailing list archives
you will find threads about using fsl_glm to remove nuisance regressors (e.g.
motion parameters) prior to ICA. You will also find a discussion of how to
incorporate nuiscance regressors into dual regression.
As Stephen Smith recently pointed out, if you still really want to use
fsl_regfilt, you could consider doing ICA in two stages. First do ICA on each
subject individually, identify individual noise components, and remove them
with fsl_regfilt. Then take the filtered data and do your tcICA on that. This
is a lot of work, though!
