Dear Ruopeng,

First let me thank you for making just a fantastic package. I love how it all "just works" and is so well integrated.

I do have one request tough, would it be possible to add more command line options to Trackvis to automatically do some operations? What I have in mind is:

- Loading TRK file

- Load ROI (s) from Nifti (but even one is enough for a start)

- Filter fibers by ROI (maybe length too if possible)

- Save filtered fibers to a new TRK file

I know I can do this with some homemade Python or MATLAB scripts. Even the UCLA Multimodal connectivity package already does do this, but even they claim that the number of found fibers is only 95-99% similar to Trackvis. Also having the GUI quickly load up with the fibers  up would be very good, to quickly check problem cases. Again it's all a question of having all the process well integrated.

I wonder if this functionality would be already be possible via the Network remote access option. Is the protocol for that documented somewhere? That would be amazing.

A great big thanks!
