ENH: add flexibility in run_getroicorrs to deal with session labels and nuisance regression options #103
Description
Summary
run_getroicorrs will work fine for compcor_global option, where there is no session label in the bids directory tree.
Expected behavior
It would be preferable to also have flexibility to dynamically call nuisance regression option and add session label.
Script/Workflow details
Need a fix here. Should be able to add nuisance regression option as an argument. Sessions could either be added as layers to the loops or added to subject list, which would also naturally then get fed to the subject_roi-pair_corr.csv file.
