Dear FreeSurfer experts,

I am trying to perform a retinotopy analysis using fs-fast with Freesurfer version 7.3.2 on a Mac OS Monterey Version 12.6.2

Here is the error I am having (I saw this same error in the archive, but I wasn't able to find any solution email that followed regarding this issue):

Saving X matrix to /Users/tong_processor/Desktop/Loic/retinotopy/old_Hojin_mri_data/F094_fsfast/sess01/bold/retinotopy.F094.07.lh/pr007/Xtmp.mat

Error using svdInput to SVD must not contain NaN or Inf.Error in cond (line 35) s = svd(A);Error in fast_selxavg3b (line 389) XCond = cond(XtX);Error in sxa3 (line 9)

fast_selxavg3b('/Users/tong_processor/Desktop/Loic/retinotopy/old_Hojin_mri_data/F094_fsfast/sess01/bold/retinotopy.F094.07.lh/sxa3.config.txt')

Error in run (line 91)

evalin('caller', strcat(script, ';'));

Please see attached the code I used, and the associated files of the analysis

Thanks in advance for your help!
