Hello,

Trying to run this on two samples. It had been running for a while and then finally errored out after tabulating control merged start positions.

This is a regex version problem. Upgrade regex will solve the problem. For example conda install -c conda-forge regex

Let me know any problem.

Thanks, Yichao

Update

conda install -c conda-forge regex did not work.

conda install -c anaconda regex=2019.12.9 solved the problem.
