Ok great! Thanks for the quick responses, and for your help.
Best, Krista

no, those are whole-brain parcellations so ever vertex is already assigned the most likely label for it

Ok perfect. Just one last question, how would I use the thresholded option
for the annotations (i.e. aparc.DKTatlas40.annot, aparc2009s.annot) when doing whole brain analyses? Thanks!

Great thanks Bruce! I'm assuming then that using the thresh.label is the best choice.

The .thresh ones are thresholded to pick the most likely vertices that give a label that is the right surface area. cheers Bruce On Sun, 17 Nov 2013, krista kelly wrote: Hi, I've just started using the newest freesurfer v 5.3 and I've noticed in the labels folder that every .label has a thresh.label. When overlaying the two, they can be quite different (for example MT.label is much larger than MT.thresh.label) or quite similar (V1.label is just a tiny bit larger than V1.thresh.label). What is the difference between the two and which is best to use? Thanks! Krista The information in this e-mail is intended only for the person to whom it is addressed.
