Hi Doug. Yup, the FDR button is working for me in tkmedit. I see the mask to brain, but as you can probably guess I'm interested in masking to the basal ganglia.

Yea, there's not a mask to label. There is a mask to brain, but I'm not sure if you can substitute your own mask for it. I just tried to run it, and could not get FDR to work at all in tkmedit. Is it working for you at all?

Dear FreeSurfers,

I've created a basal ganglia label and am wondering if it's possible to constrain the FDR calculation to that label? Based on earlier messages it seems like tksurfer has a "marked label only" option for FDR, but I haven't been able to find something similar in tkmedit. Any help greatly appreciated.

Thanks!
