Hi all,
I
used QDEC compare differences between normal subjects and patients, the activation can be seen without correction, after correction by FDR ,all disappeared. I read about the Clusterwise Correction for Multiple Comparisons of the manual. I am confused about the meaning of Correction. I use the simulation when an error is as follows:
#############################################################################################
ERROR: dimension mismatch between X and contrast /usr/local/freesurfer/subjects/sad/qdec/Untitled/tmp.mri_glmfit-sim-2797/lh-Avg-Intercept-area.mtx X has 8 cols, C has 2 cols
#############################################################################################
Why is that? Also could you please give some recommendations on the correction.
Thanks for your reply, i 'll be very grateful to you for your help.
