How to set up the preprocessing part of the chromosome

[qiqi277]

Hello, thank you very much for developing the Monopogen software.
I have encountered some problems in the running process. I run the pig sample, but when I run the preprocessing part, it shows an error because I can't find chromosome 19. What can I do to make it work with only the first 18 chromosomes? Here is my error message.

`multiprocessing.pool.RemoteTraceback: 
Traceback (most recent call last):
  File "/public/home/zhangqiqi02/miniconda3/envs/momopogen2_env/lib/python3.9/multiprocessing/pool.py", line 125, in worker
    result = (True, func(*args, **kwds))

    return list(map(*args))

  File "pysam/libchtslib.pyx", line 683, in pysam.libchtslib.HTSFile.parse_region
ValueError: invalid contig `19`

The above exception was the direct cause of the following exception:

    main()

Looking forward to your reply!
