hi again
i'm still really stuck with my retinotopy analysis as i'm not sure if my version of paint-sess $Id: paint-sess,v 1.2 2003/08/06 00:53:50 greve Exp $ FAST Version 20031218) has a bug in it (it doesn't make the field sign map). i originally downloaded freesurfer-20040218-Linux.tar.gz (for RedHat 9).
also, can someone also confrim the colour coding is: red=upper field/fovea, blue=horizontal meridian/parafovea, green=lower visual field/periphery?
i can't work out what the overlay threshold settings should be in tksurfer to correctly display the colours to code the retinotopy, is there some rationale for choosing them?
thanks a lot for your help!

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!
