Hi,

Sorry to resend this email, but I tried all the solutions listed on the help page but they don't work. My graphics card is an Intel Mobile 4 Series Chipset Integrated Graphics Controller. How do I update the drivers?

Jon

have you tried updating your video drivers? Freeview doesn't currently have any tools for tracing on the surface, I don't think.

Hi,

I have a laptop equipped with Centos and Freesurfer but I can't get tksurfer to properly display the surface files of either the fsaverage brain or individual subjects. The surfaces are either small portions of cortex or an assemblage of lines/dots. I have attached a few tiff files as examples. Is there something I can do to fix this? I have tried using freeview instead, and the surfaces do display properly, but the program does not seem to allow me to trace label files. Is there another way around this? Does a newer version of freeview include tracing ability?

Thanks, Jon
