Can you send the command line, the sum file, and a pic of the surface?

Dear Freesurfer experts,
I have run an analysis on GM Volume in Freesurfer.
The interested contrast was patients vs. controls. (/command mri_glimfit/)
I then ran /mri_surfcluster/ command to get a text file with the significant clusters FDRcorrected and their peak coordinatesn- resulting in a *sig.mgh image* and a *sig.sum file*.
*After looking at the sig.mgh image with tksurfer and searching for the significant clusters in the sig.sum files, I realized that one cluster which is pretty big is missing in the sig.mgh image but is present in the sig.sum file.*
*Do you know why this could happen?Why is the image incomplete?*
*Anybody encounterd something similar?*
Because in the next step I want to extract the values of the significant clusters and correlate them with clinical scores, it would be good if thenumber of clusters in the result image and the result file coincide.
Thanks in advance for your help.
Best,
Georgiana
