Thank you, Dr. Greve. when I ran >2000 subjects in Version 5.3, I received this error message "##ERROR: gdfReadV1: the number of inputs in FSGD file exceeds the maximum allowed 2000##" In your previous post about mri_glmfit, https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2013-September/033151..., I found #define FSGDF_NCLASSES_MAX 128 #define FSGDF_NVARS_MAX 128 #define FSGDF_NINPUTS_MAX 2000 Are these the maximum? The mri_glmfit is written in C. Could you send me a version of mri_glmfit code without limits? Thank you very much.
Xin

I don't think there is a maximum size. You would do the big analysis the same way as the small.

Hello, FreeSurfer Group,
What is the maximal matrix size for glm_fit process?
How to use FreeSurfer for group analyses of more than 2000 subjects, 128 variables, and 128 Classes?
Thank you.
