Dear FreeSurfer experts,

I'm trying to analyze some monkey functional data. I got this error message with selxavg3-sess.

I run the following commands:

mkcontrast-sess -analysis FF-MonkeyCassis.sm03.lh -contrast ON-vs-OFF -a 1 -c 0
mkcontrast-sess -analysis FF-MonkeyCassis.sm03.rh -contrast ON-vs-OFF -a 1 -c 0
preproc-sess -surface MonkeyCassis lhrh -fwhm 3 -s MonkeyCassis-FF -fsd bold -per-session
selxavg3-sess -a FF-MonkeyCassis.sm03.lh -s MonkeyCassis-FF

------- matlab output --------------------
MATLAB is selecting SOFTWARE OPENGL rendering.
