extracting streamlines based on sift2 weight

Good morning all,
I am new to MRtrix3, have started working with .tck files recently and would like to extract streamlines based SIFT2 weight, such as extract all the streamlines that weight is higher than 0.1. Does such a function exist?

Thank you!

Hi Jianzhong,
Welcome the forum!

Check out tckedit

Something like this might work:
tckedit <tracks_in.tck> <tracks_out.tck> -tck_weights_in <input_weights_file> -tck_weights_out <output_weights_file> -minweight 0.1

Hope this helps!
