Re: [Freesurfer] spatial scale bar question

Hi Ruopeng

Thanks for your reply.

I have a question though. When I zoom in the 3D image, the scale bar numbers don't change. Shouldn't they change when I zoom in?

Thanks

Hi Mona,

If you are running the latest dev build, you can right click in the 3D view and choose “Show 3D scale”. The scale bars can only be placed at the boundary of the FOV.

Best, Ruopeng

Hi Freesurfer experts

I wanted to follow up on my question about "spatial scale bar" for significancy maps in FS. I appreciate if you let me know about the updates on that.

Thanks Mona

Hi Mona

sure. As I said it is a bit more complicated than it seems. Ruopeng will post a note when something usable is in the dev version

Yes Bruce.

It doesn't work.

I appreciate if you could let me know when you had any updates on it.

Thanks

  I have overlaid the significance map on an inflated brain, and I don't see the scale

  Dear Freesurfers

  Hi


  I am trying to add a spatial scale bar to my cortical maps in tksurfer. However,
  as it's mentioned in Freesurfer forum before, the scale bar in tksurfer shrinks
  when you zoom in the brain.

  I couldn't find a scale bar option in Freeview neither.

  I appreciate if you could let me know how to get a scale bar.


  Thanks
