There is a new retinotopic mapping stream. I have not fully documented
it yet. You now analyze the retinotopy data like you would other
functional analysis in fsfast. First create an "analysis" with
mkanalysis-sess. Run it with -help to get info on retinotopy-specific
parameters. Eg,
# Create analysis for the left hemi (30 sec period), 5mm surface-based
smoothing
mkanalysis-sess -a rtopy.lh -surface self lh -TR 2 \
-retinotopy 30 -paradigm rtopy.par -fwhm 5
# Create analysis for the right hemi
mkanalysis-sess -a rtopy.rh -surface self rh -TR 2 \
-retinotopy 30 -paradigm rtopy.par -fwhm 5
# Analyze both (this will do preprocessing too)
selxavg3-sess -a rtopy.lh -sf ...
selxavg3-sess -a rtopy.rh -sf ...
# diplay sig maps
tksurfer-sess -a rtopy.lh -s sessid
# display raw angle
tksurfer-sess -a rtopy.lh -s sessid -map angle
# display raw angle
tksurfer-sess -a rtopy.lh -s sessid -map angle.masked
# create the field sign
fieldsign-sess -a rtopy.lh -s sessid -occip
# display the field sign
tksurfer-sess -a rtopy.lh -s sessid -fieldsign
