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!
