Sorry for multiple responses, but thank you for clarifying me issue, R. I will contact my informatics hub for further assistance since the issue is more to do with the software I am using.
Thank you for your assistance Best wishes Zola

Hi Doug, three years later and an order of magnitude more subjects. Any chance you could raise the limit of maximum number of subjects further (>60K)?
Thanks a lot, Inge _________________________________________ Inge Kasbohm Amlien, PhD Center for Lifespan Changes in Brain and Cognition University of Oslo, Norway

The mri_glmfit is written in C. Could you send me a version of mri_glmfit code without limits? Thank you very much.

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

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.
