it does not have that option, so you'd have to split

Hello all,
I am wondering if the FS FAST retinotopy analysis can deal with
within-run alternations of stimulus direction. I have collected data
in which eccentricity and polar angle were manipulated in separate
runs, but within each run, a cycle of stimulation in one direction was
followed by a cycle in the opposite direction. For example, 32 s of
clockwise-rotating wedges were followed by 32 s of counterclockwise
wedges, etc. I realize now that this may not have been a wise
choice--does FS FAST have some paradigm file option for alternating
stimulation? If not, is my best solution to cut and splice my runs,
dividing each into two mini-runs of single-direction stimulation?
Thanks,
Jeff
