Dear FreeSurfer Developers,

I am trying to do FSFAST analysis on Mac OS Catalina 10.15.3, and I have completed the preprocessing (preproc-sess, mkanalysis-sess and mkcontrast-sess) with no problem. When I ran the function selxavg3-sess, it proceeded somehow (-->preproc-sess done--> MATLAB opened and then was closed), but when it started running fast_selxavg3b it stopped after a while (fast_selxavg3() failed\n) with the following errors: 

Extension format = nii.gz

INFO: key nSliceGroups unrecognized, line 12, skipping

1 AnimalvsNonAnimal.mat

Excluding 4 points

Subscript indices must either be real positive integers or logicals.

 

Error in fast_st2fir (line 118)

      Xfirss(ind,nthd) = wstim;

 

Error in flac_desmat (line 58)

      flacnew.ev(nthev).Xfir = fast_st2fir(st,ntpssr,TER,ev.psdwin,useweight);

 

Error in flac_customize (line 357)

flacnew = flac_desmat(flacnew);

 

Error in fast_selxavg3b (line 129)

flac0 = flac_customize(flac0);

 

Could anyone help me with this problem, please?

 

Best Regards,

Mahdiyeh
