Unfortunately, the way I have the retinotopy analysis set up, both polar
and eccen must be there. However, you can just copy the polar into a new
folder and call it eccen and it should complete. Then you can ignore the
eccen part.

Hello,
I am trying to run a retinotopy analysis in fsfast, using only polar
angle. However, when I try to run it, I am getting the error "Input to
SVD must not contain NaN or Inf." I have traced this error and it
looks like the design matrix X has 12 regressors (the first 12) that
consist solely of zeros. I am using the following commands:
mkanalysis-sess -analysis retinotopy -fsd bold -runlistfile runlist.txt
-native -funcstem fmc -nuisreg mcextreg 3
-retinotopy 36.4 -per-session -paradigm retino.par -inorm
-spmhrf 0 -TR .650 -polyfit 2 -nskip 19
selxavg3-sess -analysis retinotopy -sf sublist.txt -df sessdir
Any idea what the first 12 regressors in the design matrix might
correspond to in retinotopy analyses and why they'd be empty? I have
looked at the documentation and there doesn't seem to be a clear
labeling of the retinotopy design matrix anywhere, although perhaps
I'm missing something.
Thank you very much,
JohnMark
