Hi gabriele
when you say they are white crosses, what does that mean? Is the volume binary? You might try loading it as a segmentation volume. The labels won't be meaningful, but they will show up as a different color with the rest of the volume transparent. You could also try using freeview, which is far more flexible.

Dear freesurfer experts, I was wondering if there's an easy way to visualize contacts of intra-cerebral electrodes within tkmedit.
Here's the scene: I've got a volume, which contains a white cross for each contacts on some linear intra-cerebral electrodes. This volume is in nifti format. I'd like to visualize it as an overlay to the orig volume and add also pial border in order to identify which contacts lay in white matter and which ones not. I've tried adding the nifti voulme as a functional overlay but I cannot see anything maybe is only a setting problem for the color-scheme. I've tried to modify the settings inside the View Menu for the functional overlay but nothing happen (maybe because it expects to have functional data not a binary mask).
Is there an easy way to accomplish my task?
Best regards, previously coregistered to orig.mgz, gabriele
