Design matrix, not contrast matrix. It was printed out as part of the terminal output. It can also be found in glmdir/Xg.dat On 05/26/2016 01:48 PM, Hanbyul Cho wrote: > Dear Douglas N Greve, > > The Contrast matrix was = [1 -1 0 0 0 0] > I attached the Xg.dat printed by unended mri_glmfit proces

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.glm
