Dear,

We also noticed a bad segmentation in another subject in the frontal cortex (see attached figure) which was correctly done using CAT12. Can we change some parameters to fix this?

Thank you

Kind regards

Dear, 

In the attachment the figures.The surface placement is ok. The cautate is smaller than the segmentation.

Kind regards

The caudate segmentation would not affect the surface placement. Is the surface placement ok? Can you send a pic of the caudate error?

The subcortical structures were not delineated correctly, especially the nucleus caudatus which had a lot of atrophy in this particular patient group.

I don't think CAT creates white or pial surfaces, so no. What is wrong with your FS analysis?

Dear,

The segmentation using Freesurfer was incorrect, however we have a good segmentation from Cat 12. Can we use this segmentation for PVC in PETsurfer?

Kind regards
