Hi FreeSurfer team,

 

I am currently trying to run a correlational analysis in FreeSurfer. I am able to run the preproc and mri_glmfit commands successfully, but I am getting error messages when running mri_glmfit-sim for lGI, thickness and area. An example error message is: ERROR: cannot find /usr/local/freesurfer6/freesurfer//average/mult-comp-cor/fsaverage/rh/cortex/fwhm55/abs/th40/mc-z.csd. I have attached the full terminal output so that you can see the variations of this error message that I am getting. Are you able to advise what the issue might be and how I might go about fixing the issue? Just for reference, I am using a smoothing value of 10 for volume, area and thickness, and 5 for lGI. I would also be happy to share my design matrix and scripts if that would make the troubleshooting easier.

 

Thank you in advance for any help you can offer.

 

Best wishes,
