Hi there,
I have some simple questions regarding probtrackx options, I am sure have been asked before however I couldn't find them in the archives.
1.) For training purposes, I used a unilateral BA4 mask (motor cortex) as seed mask, and selected as waypoint and termination mask a medulla mask to get the cortico-spinal tract. The fdt_paths result looks a bit messy, however if I threshold at 50 it looks quite nice. I think that's Ok to do as I remove low probability voxels. Is this right?
2.) What would the settings be if wanted to use the classification option, and fdt_paths should look the same as in 1.), ie. would I need to specify the termination and waypoint masks as above?
I hope these questions make sense.
Thanks for any input.
Cheers,
Torsten
