Hi Ruthi

you need to sample them onto the surface to get vertex indices. The easiest way is to just load it into tksurfer then write it out

Hi all,

I am creating a label file using the select voxels tool in TkMedit. However this doesn't work properly with e.g. all saved vertex IDs are set to -1.

Example file: #!ascii label ….. , from subject ….. vox2ras=TkReg 19 -1 -40.000 52.000 21.000 110.0000000000 -1 -39.000 52.000 21.000 110.0000000000 -1 -38.000 52.000 21.000 110.0000000000 -1 -37.000 52.000 21.000 110.0000000000 -1 -37.000 52.000 19.000 110.0000000000 -1 -37.000 52.000 17.000 102.0000000000 -1 -38.000 52.000 17.000 108.0000000000 -1 -39.000 52.000 18.000 110.0000000000 -1 -39.000 52.000 19.000 110.0000000000 -1 -39.000 52.000 20.000 110.0000000000 -1 -38.000 52.000 20.000 110.0000000000 -1 -38.000 52.000 19.000 110.0000000000 -1 -38.000 52.000 23.000 110.0000000000 -1 -38.000 52.000 22.000 110.0000000000 -1 -37.000 52.000 22.000 109.0000000000 -1 -37.000 52.000 20.000 110.0000000000 -1 -39.000 52.000 22.000 110.0000000000 -1 -39.000 52.000 24.000 108.0000000000 -1 -39.000 52.000 23.000 110.0000000000

Any ideas how this can be solved?

Many thanks in advance!

Best, ruthi
