That is the right one, as far as I know.

Matt Glasser or Michael Harms may know tweakable parameters, but I do not, 
unfortunately.  Not sure how accessible they are this week (holiday break).

I wonder if it might be worth posing your question to the Freesurfer list, as 
it is really a Freesurfer segmentation issue, as I understand it.  They might 
want you to try a newer version, though, and I'm not sure what downstream 
effects this will have on the pipeline.
