Hi Yufeng, it cannot handle only a single run. You must have both polar and eccen. You can "fool" it by copying your polar run into another run and calling it eccen. doug ps. Please remember to send email to the list and not to me personally. Thanks!

Hi Doug, Thank you for your patient. I am doing retinotopy analysis by using freesurfer 5.1 with the help of the webside http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis . And my problem is as followed while doing selxavg3-sess -s Sess01 -a fmcpr.sm5.self.lh.nii.gz My mmkanalysis-sess code is as followed: mmkanalysis-sess -fsd bold -stc odd -surface self lh -fwhm 5 -retinotopy 32 -paradigm rtopy.par -analysis fmcpr.sm5.self.lh.nii.gz -TR 2
Error information Saving X matrix to /usr/local/freesurfer/stable5/retinotopy_002/Sess01/bold/fmcpr.odd.sm5.fsaverage.lh.nii.gz/Xtmp.mat ??? Error using ==> svd Input to SVD must not contain NaN or Inf.
Error in ==> cond at 40 s = svd(A);

I just have one run and the rtopy.par is stimtype polar
direction neg
I attach the analysis.info and Xtmp.mat on the email. Thanks very much. Yours Yufeng
