Dear Douglas N Greve, Today, I tested the previous group analysis on other computer, and saw the same error massage.
I attached the tested fsgd and mtx files. command: mri_glmfit --y 052416_lh.Pa_Co_G2V2_dods_sm15.mgh --fsgd 052416_PA_CO_G2V2.fsgd dods --glmdir 052416_lh.Pa_Co_G2V2_dods_sm15.glmdir --cortex --surf fsaverage lh --C 052416_contrast.mtx Thank you, Best wishes, Han On Mon, May 23, 2016 at 12:56 PM, Douglas N Greve <gr...@nmr.mgh.harvard.edu > wrote: > If you seek help with this problem, make sure to send: > 1.
