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.html, 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.

Xin
