Problem with running test dataset

[boazkalk]

Hello,

I want to set up the COMMIT2 filtering for my mrtrix tractograms. First I wanted to run the "test dataset" but I get the following error:
Traceback (most recent call last):
File "/Users/bkalkhov/Tractography/Tractography_performance_testing/Tests/Commit2test/Demo_data/test.py", line 84, in
regnorms = [commit.solvers.group_sparsity, commit.solvers.non_negative, commit.solvers.non_negative],
AttributeError: module 'commit.solvers' has no attribute 'group_sparsity'
If I look into the commit.solvers it indeed does not have attribute group_sparsity but also the commit.solvers.non_negative is not there...

Is this an old tutorial and which regnorms are working/should I use?

Thanks in advance
