hi again
I have been proceeding with the retinotopy analysis using FsFast, following the
instructions at:
https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis
and i believe i have successfully overlaid the results on my surfaces and now
have two questions:
i wasn't able to create the fieldsign with 'paint-sess' because it couldn't find
tksurfer.new. when i run 'surf-sess' i use the flag -old which forces it to use
tksurfer.old but this doesn't work in the former case. how can i make
'paint-sess' use tksurfer.old and thus create the fieldsign?
there are no instructions on how to relate the colours seen when viewing eccen
and polar to the location of the ring and wedge. is there a map somewhere that
can be loaded that tells me what order the colours run from fovea to periphery
and from vertical to horizontal meridian etc.?
thanks again for your help!
jane
