[Freesurfer] tksurfer marking nodes on opposite side of brain
Hi everyone, I'm currently hand-drawing some labels using tksurfer. Unfortunately, quite often a node that I try to click will not be selected. Instead, the mark is placed on the surface behind the one I'm viewing, e.g. when trying to outline calcarine structures, the node mark will appear somewhere on the lateral surface. I wonder if anyone else has run into this? Is it possible to constrain tksurfer's node selection to the currently visible part of the cortex only? Alternatively, an undo feature to de-select the last point clicked would save me re-drawing the whole outline, but in my Edit menu, tksurfer consistently says Nothing to Undo. Do I need to enalbe the Undo feature somewhere? I'm running FS 3.0.3 centos4. Thank you very much, Johannes ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer

I think the version that you have supports individual deslecting. Try middle-clicking a selected vertex. You may need to redraw the surface to see if it was deselected.

[Freesurfer] FW: field sign and colour lables
I have a question regarding colour labelling for the retinotopic maps generated by Freesurfer. Im running Freesurfer-Linux-rh9-stable-pub-v3.0.2 and have successfully generated the polar, eccen, and field sign maps (no errors). The images seem to differentiate the occipital regions, except that the colour labelling appears to be incorrect. In the eccen image, for example, the order of the colours start out as red, green, blue and using the Configure Overlay Display Inverse its green, blue, red. According to my notes one should see fovea=red, parafoveal=blue and periphery=green. Also, with the field sign image, the area that should be V1 shows up as blue instead of yellow (cant seem to invert the colours). Ive since gone back to double check that my procedure is correct and re-checked my registration and cant seem to find my mistake. I was hoping to get some help to fix this problem. In case it helps, Ive attached a few images of the maps that were generated.
