hi doug
i'm not sure how to find out what the version of freesurfer is as the -all-info command doesn't work on csurf. however, the installation tar file i originally downloaded was called: freesurfer-20040218-Linux.tar.gz (for RedHat 9)
my paint-sess log says the version of paint-sess is:
$Id: paint-sess,v 1.2 2003/08/06 00:53:50 greve Exp $ FAST Version 20031218
are only 3 colours (red=upper field/fovea, blue=horizontal meridian/parafovea, green=lower visual field/periphery) used to specify the polar angle and eccentricity? what should the overlay threshold settings be in tksurfer to correctly display them?
thanks!
Jane

What version of freesurfer (and paint-sess) are you using? This was a problem in some versions about 6 mo ago, but I thought I fixed them all.

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!
