Yolanda, don't run mris_anatomical_stats on fsaverage. You should map the label to each individual with mri_label2label, then use mris_anatomical_stats. Sorry for not being clearer eariler. doug Yolanda Vives wrote: > Hi Bruce, > > That's the error: > > limiting computations to label > fsaverag

Hi Yolanda, you need to email us the screen output with the error so we can diagnose it. cheers Bruce On Thu, 28 Jul 2011, Yolanda Vives wrote: > Thank you Douglas for your suggestions! > > If I use mris_anatomical_stats, would I perform the following procedure? > > - To run "mri_label2label"

Thank you Douglas for your suggestions! If I use mris_anatomical_stats, would I perform the following procedure? - To run "mri_label2label" to all the subjects of my comparison - To run mris_anatomical_stats. I would obtain the volume of the labels in each subject - Mean volume of all the subject

Hi Yolanda, don't use thmax (it will exclude everything with a sig>7 -- not what you want I assume). That command otherwise looks right, but it won't correct for multiple comparisons. You can run mris_anatomical_stats on the output label to give you the stats you want. doug Yolanda Vives wrot

Dear freesurfers, I would like to obtain the cluster size (in mm3) and coordinates of the maxima of a cortical volume comparison using mri_surfcluster. mri_surfcluster --in $PATH/control_cronic_dones_right_volume/rh-Diff-control-cronic-Intercept-volume/sig.mgh --hemi rh --subject fsaverage --thmi
