Dear Freesurfers,
I used the following command line to find significant clusters after glm analysis (before MC clusters attached)
mri_glmfit-sim \ --glmdir lh.meditation_age.glmdir \ --sim mc-z 5 4 mc-z.negative \ --sim-sign neg --cwpvalthresh 0.05\ --overwrite
I didn't find any, i.e., there are no clusters listed in file mc-z.negative.sig.cluster.summary. Does this mean that I should accept the null hypothesis for the whole cortex?
Also, how many iterations of mc do people typically perform? I guess it doesn't make a difference if I do 1000 iterations instead of 5 anyways.
Thank you very much!
Sincerely, Ye
