Hi, Bruce and Douglas. Thanks for your patient reply. I have checked the problem with the latest freesurfer, but the problem is still there. Now I am sure that what I get with the tksurfer is a up-down mirror image (see the attached). If the image is put upside down, it will be ok. As I know, in normal condition, the color bar is actually located at the bottom right corner.
This is a weired problem. If you would like to help me solve this problem, I will appreciated it. If not, I think I can also use it for visualization now with a subsequent flip.
Thanks very much.
Xiangzhen

** The system is CentOS release 6.3. And the package of freesufer is freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0. I wonder whether the version mismatch(centos4 vs.centos6) causes this strange problem. I think I have to check this. (As I remember, tksurfer of this version works well in centos5.7)
PS: tkmedit works well with volumetric data. And freeview also works well.

I didn't notice this before but your entire color scale bar (including the text!) is mirror imaged. This is very strange, and probably explains why it looks like an rh. Can you give us the details of your environment. I don't have a clue what would cause this. Does the tkmedit
window look correct? Freeview? Make sure that the text is not mirror-imaged as in this figure you sent

The image is attached. The following cmd is all I did. tksurfer fsaverage lh inflated -overlay ./fwhm10lh/c1.contrast/sig.mgh And I did not click any button.
I think the image is likely just a mirror image, but I failed to find a "invert" button. Where is the "invert" button?
Best!

Do you mean the threshold? min=2.0 max=5.0

Thanks very much.
Another problem, do you know why the color bar is inversed in my first email? Might it be related to the right-left weird problem?

There is no config that would do that. Fsaverage is somewhat unique in

the lh and rh have the same number of vertices. All I can think of is t

download it again and see if that fixes your problem Bruce

Actually when I just use "tksurfer fsaverage lh inflated", there is the similar problem. And fsaverage was copied from freesufer by recon-all. So I think there might be something wrong with using tksurfer, e.g., config.

Hi all.I want to display a result with tksurfer. The cmd is here: tksurfer fsaverage lh inflated -overlay ./fwhm10lh/c1.contrast/sig.mgh That is, I want to display the result of the left hemi. However, to my surprise, the plot seems like on the right hemi of the brain. In addition, the color bar is also strange. The plot is attached. I wonder whether this is normal or something may be wrong.
