Hi Katie, do you have eccentricity runs as well or just polar?

I was trying to do retinotopic analysis on a dataset using the new Freesurfer v5.0.0 on a 64bit Linux (Red Hat 4.1.2-48 CentOS 5.5) computer and have run across a problem.
I set up the analysis using mkanalysis-sess as suggested in an earlier email to the list, but when I try to run selxavg3-sess it errors out.
The commands I ran were: mkanalysis-sess -analysis retino26-lh -surface self lh -fwhm 0 -retinotopy 55.467 -paradigm retino.par -TR 2.6 -runlistfile polar_runs.txt selxavg3-sess -a retino26-lh -s spicyrobin -df retino-dirfile
It gets through all the preprocessing and then this is the output (the matlab error is one I know about, if that is causing the problem I can talk to our IT here about getting it fixed):
preproc-sess done
