read_trk_to_fg Error: Index exceeds matrix dimensions

[maohy915]

Hi there, I got an error when I try to use read_trk_to_fg script.

I use mrTrix3 generate .trk file (whole brain track), then I 'm going to process data in AFQ. The .trk file shows weel in mrview, but does't work well with read_trk_to_fg script.

Hi, if I remember correctly there is a mismatch between mrtrix writing and reading versions. Please check that you are using the same versions for both writing and reading

Oh, I don't know what's wrong with it. And the code were download from GitHub repositories(https://github.com/vistalab/vistasoft)
I find dtiImportFibersMrtrix works well to read .tck file, but there is a little bug. When I use fg=dtiImportFibersMrtrix('trackfile.tck') import mrtrix trackfile, the fibers value in fg.fibers is single, which should be double. At this point, MATLAB will report an error when I run AFQ_SegmentFiberGroups.
