error: cell-by-peak matrix

[Qingrun]

I have a problem with Step 12. Create a cell-by-peak matrix.
I kept on getting problem like the following:
***** WARNING: File /tmp/tmplgxoCq has inconsistent naming convention for record:
chr4 101347707 101347797 AAACGAAAGACACGGT-1

I searched for the previous solution like this one: #154.

I tried to install snaptools, python/2.7 into a new miniconda environment , but still didn't work. Maybe I missed installing the right dependencies. May I ask how to solve this problem?

Thanks.
