Re: [Freesurfer] two labels in tksurfer/freeview?

that's a good way to do it. You don't even need to save it as an mgz. You can just do tools->labels->copy label stats to overlay, then delete the label and you have an overlay from it (assuming the label->stat field is not zero) On Thu, 27 Feb 2014, Yang, Daniel wrote:

Thanks for both of you for the helps! I also find a 3rd solution: convert one of the labels to mgh and thus use it as overlay and use the other one as label in freeview.

Doug: Creating an outlined label sounds pretty cool. I wonder whether either erosion or dilution would do the trick … some sort of tricky conjunction.

Bruce: thanks!!

  the other thing you could do is draw a path in tksurfer and have

the "outline", then load the inner label and display it as filled On Wed, 26 Feb 2014, Douglas N Greve wrote:

Thanks for your reply! In the annotation, can one of the label be just outlined and the other filled?

I would really appreciate if you could provide a step-by-step example for this one… esp. how to create the colorLUT in this case...

Best, Daniel

I'm not sure about freeview, but you cannot do it in tksurfer. You      can      take your two labels and create an annotation with      mris_label2annot (you      get to specify the color)

Dear FreeSurfer experts,

Is it possible to display two labels in tksurfer or freeview,          where          one label is outlined with a certain color and the other label is          filled with a different color?

I want to show two labels, one is within the other one.

If yes, could you please tell me the specific steps..?

thanks a lot!          Daniel
