Failure on MRTrix2TrackVis with nipype 0.13 but not the older 0.12

[dorianps]

Summary

The same code fails if I use the developer version of nipype 0.13 but works with the older release 0.12.
Sorry for not giving too much details, it's my first time using nipype and I did not keep track of everything (who would have thought that it was the nipype version).

Actual behavior

The ".trk" file produce with the new version is 1kb with nothing in it. It loads in TrackVis but has not streamlines to show.

Expected behavior

The ".trk" file should be dependent on the number of streamlines, and larger than 1kb. It should also be loadable in TrackVis.

How to replicate the behavior

tck2trk = mrt.MRTrix2TrackVis()
tck2trk.inputs.in_file = 'temp.tck'
tck2trk.inputs.image_file = 'meanb0.nii.gz'
tck2trk.inputs.out_filename = 'temp.trk'
tck2trk.run()

Platform details:

please paste the output of: python -c "import nipype; print(nipype.get_info())"
This is what's working well.

I am trying to upload a zip file to help you replicate the error but it's not allowing it.

Hi @dorianps,
This seems weird, if you could share some data with me to replicate this I'd like to take a look

Follow up: I have installed nipype in 3-4 computers in the last two days, and I finally realized that all packages need to be updated for the Trackvis conversion to work. That said, once everything works on nipype 0.12.1 upgrading to 0.13 brings a charset error, as below.
