Hi Doug,

Thank you for reply. yes all 4 are in bold separately.
I tried -run-wise with selxavg3-sess, but it failed with the following msg:
Saving X matrix to /media/local_home/zhouw4/EM0220/analysis/retinotopy/SUBJ01/bold/rtopy.self.lh/pr001/Xtmp.mat
Error using svd
Input to SVD must not contain NaN or Inf.

Error in cond (line 39)
   s = svd(A);

Error in fast_selxavg3 (line 254)
  XCond = cond(XtX);

I attach the mat file in the email. I am thinking that the error is similar as that I only put polar or eccen session in bold folder. Thank you for looking into it.

Best
Wei
________________
But all four runs into a single bold folder, then try running 
selxavg3-sess with the -run-wise option. This will create separate run 
analysis in the output directory. I have not tried it with retinotopy 
before, so get back to me if it fails.
