When you are editing the segmentation, are you using the middle button
to change the label?

Hi Jared,
How are you selecting the segmentation that you wish to be changing
it to? Have you opened the Segmentation Bruch Info dialog window and
selected from the list in there?

In response to the questions, I do see the segmentation properly in
colors (as a translucent color overlay on the anatomical), and I am
sure I am using the Edit Segmentation tool. Clicking and dragging
with the tool does change the segmentation volume, it just does not
change it to the "Sgmtn label" (in the tools window) that I want.
It doesn't matter what value I choose in the Segmentation Brush
Info, the "Sgmtn label" line says "Right-accumbens-intens" and the
paint is grey or white depending on the background color of the
segmentation label map. Any further ideas? Thanks.

Sorry, I was thinking you were talking about Scuba.
Do you see the segmentation properly, in colors? If not, there was
probably an error in loading the segmentation; do you see any errors
in the shell window?
If you do see the segmentation volume displayed properly as a
translucent color overlay on the anatomical, are you sure you are
using the Edit Segmentation tool? It's a paintbrush over a volume
divided into quarters.
Does clicking and dragging with the tool actually change the
segmentation volume, that is, can you mouse over the edited voxels
and
verify that the values in the "Sgmtn label" line in the tools window
matches the value you selected in the Segmentation Brush Info dialog?

Yes, I believe so. The layer's color map is set to
FreeSurferColorLUT.txt when loading the segmentation. The
Segmentation Brush source is set at Segmentation (under Configure
Segmentation Brush)--I imagine that's what you are referring to
when you say "target layer."

Are you sure the Target Layer is set to the segmentation volume

I am attempting to edit the segmentation results in TkMedit,
according to the following Wiki directions ( >
TkMeditGuide/TkMeditWorkingWithData/TkMeditSegmentations):
A segmentation can be edited with the Edit Segmentation tool,
which can be activated by pushing the icon_copy.gif button on
the Main Toolbar, by choosing *Tools->Edit Segmentation*, or by
pressing the 'g' key.
By clicking with button 2 with this tool, you can 'paint' a
label in the segmentation. The color used can be set in the
dialog box brought up by choosing *Tools->Configure
Segmentation Brush....* However, I am not able to change the
color to match the structure I am wanting to edit (I have tried
selecting three different structures at random and the color of
the editing remains grey). Any ideas?

Thanks, Jenni for the assistance. Yes, I have gone to
Tools/Configure Segmentation Brush.../Segmentation Brush Info in the
TkMedit Tools window. In the Segmentation Brush Info window, I have
selected my desired structure color (with the Main Anatomical used as
source) and still no change in the "Sgmnt label" when I attempt to
edit the segmentation.
Jenni,
Thanks--it was a button issue. It is working now!
I was confused because I was following the Wiki directions
(http://surfer.nmr.mgh.harvard.edu/fswiki/TkMeditGuide_2fTkMeditWorkingWithData_2fTkMeditSegmentations?action=highlight&value=TkMedit)
and on my Mac, it is Button 3 (according to System Preferences) that
paints a label in the segmentation, not Button 2 as indicated. I didn't
know what you meant by the "middle button", but I started to experiment
and discovered it was Button 3 that paints the label. Thanks again for
your help.
Should I change this Wiki page to indicate that it is Button 3 or is
this just an issue for those who use Macs with the new standard Mac mouse?
Best,
Jared
