Hi Julia, that command is fine. It will not use the fieldsign or eccen. doug On 12/10/2012 10:17 AM, Julia Foecker wrote: > Dear Doug, > > I tried version 5 with the commands suggested on the webside and this is > working > (http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnaly

Hi Julia, I don't think it looks terrible (unfortunately:). You might try increasing the smoothing level (maybe 10 fwhm). doug On 12/12/2012 08:02 AM, Julia Foecker wrote: > Hey Doug, > > thanks for your reply. I tried now the polar angle mapping for the left > hemisphere and I got the figure a
