Numerous tweaks and bug fixes re: NIRS mode and fmri refinement
Numerous tweaks and bug fixes re: NIRS mode and fmri refinement

Introduced new prenormalization mode ‘laginv’ to emphasize early time
courses
Put in new “—venousrefine” macro to bias regressor refinement to the
draining vasculature.
Fixed the output of the refine mask
Partial addition of “—cleanrefined” flag to remove neuronal signals -
doesn’t work very well, will probably back it out of later versions
unless venous refine makes it work better.
Fixed usage statement to print the actual name of the program and to
improve formatting.
Added separate “macros” area to usage.
Cleaned up despeckle option selection.
