Hey guys,
We are using mri_label2label to convert a label created from a cluster (using mri_surfcluster) from an average subject to each individual subject. We have 6 individual labels that we are converting. All of the analysis is done using surface data. I use the command in the generalized form listed below:
Mri_label2label -srcsubject fsaverage -srclabel cluster1.label -trg subject Subject -trglabel Subject_cluster1.label -regmethod surface -hemi lh
5 of the 6 labels transfer well, but a 6th label translated to the correct anatomical location, but the number of labeled vertices is greatly reduced after the translation. This problem persists across all subjects. There doesn't appear to be much interior to the label, just a lot of the outline of the label (i.e. If the outline of the label is yellow and the interior is blue, I see a lot of yellow and not much blue, as if there are a bunch of small "islands"). The region on them most inferior part of the lateral surface approximately where the temporal and occipital lobes meet.
Any ideas what might be going on?

what does the original label look like? Can you convert one of the predefined labels (eg, lh.V1.label) to see if the same thing happens?
