Hello FreeSurfer Developers,
I want to compare the relationship between age and thickness, which is controlled the effect about sex,education and eTIV, so QDEC was used. However I met a problem when I use it, such as picture1.
I get the wrong message, Error in Analyze: command failed: mri_glmfit --y /home/abby/Desktop/qdecyoung/qdec/Untitled/y.mgh --fsgd /home/abby/Desktop/qdecyoung/qdec/Untitled/qdec.fsgd dods --glmdir /home/abby/Desktop/qdecyoung/qdec/Untitled --surf fsaverage lh --label /home/abby/Desktop/qdecyoung/fsaverage/label/lh.aparc.label --C /home/abby/Desktop/qdecyoung/qdec/Untitled/contrasts/lh-Avg-Intercept-thickness.mat --C /home/abby/Desktop/qdecyoung/qdec/Untitled/contrasts/lh-Avg-thickness-age-Cor.mat --C /home/abby/Desktop/qdecyoung/qdec/Untitled/contrasts/lh-Diff-Female-Male-Intercept-thickness.mat --C /home/abby/Desktop/qdecyoung/qdec/Untitled/contrasts/lh-Diff-Female-Male-Cor-thickness-age.mat.
So I tried to put those to terminal, the feedback is:
