Hi Andreas, I have a new tool to help in retinotopy analysis. You can download it from here:

ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/sfa2fieldsign

Run it with --help to get more info on how to use it. It takes a patch as an input, but it will run using the sphere if you do not supply a patch. This gives similar results to using a patch, but you should really create a patch.

Hello

I am analysing my phase encoded retinotopic data with FS-FAST. Meanwhile everything is running fine.

However I still haven't figured out how I can find out what colours of tksurfer's overlay colourmap correspond to which phase.

Further I was wondering if it is possible to calculate an automatic fieldsign map (combining polar and eccen data) with paint-sess without having an occipital flat map.

I am grateful for any kind of hint :-)

Many thanks

best wishes

Andreas
