Hi,

I want to provide more information about the retinotopy analysis error in case someone has insight about the problem.

Using the same exact commands (mkanalysis-sess.new, then sfa-sess), I was able to successfully run the retinotopy commands in my old Linux box (the version of sfa-sess was from 2005, and we used matlab 6.5). However, the program hang using the newest version of freesurfer on Linux (the version of sfa-sess was from 2007, MATLAB 7.8). The program hang almost immediately. On Mac OS 10.6 using MATLAB 7.6, the command sfa-sess also hang with an error message of "ERROR: selfreqavg failed". I tried to replace the new sfa-sess with the old sfa-sess, and the new selfreqavg with the old selfreqavg, but the problems were not fixed.

Is there a bug in the binary files that makes them incompatible with higher versions of MATLAB, or Mac OS 10.6, or Linux 2.6.9-89.0.15.ELsmp?

Thanks for your insight.
