Errors making detection and creating reference

[RaraykinValery]

Hello! I'm trying to use WisecondorFF using reference npz which I made for WisecondorX, but I get an error:

$ python ~/bin/WisecondorFF/src/main.py detect -i npz/sample_1.npz -r ref/reference_60kb.npz -o results/sample_1
Traceback (most recent call last):
  File "/home/vray/bin/WisecondorFF/src/main.py", line 1203, in <module>
    main()
  File "/home/vray/bin/WisecondorFF/src/main.py", line 41, in wrap
    output = f(*args, **kwargs)
  File "/home/vray/bin/WisecondorFF/src/main.py", line 1199, in main
    args.func(args)

    output = f(*args, **kwargs)
  File "/home/vray/bin/WisecondorFF/src/main.py", line 864, in wcr_detect
    ref = ref_npz["reference"].item()
  File "/home/vray/miniconda3/envs/bioinfo/lib/python3.6/site-packages/numpy/lib/npyio.py", line 259, in __getitem__
    raise KeyError("%s is not a file in the archive" % key)
KeyError: 'reference is not a file in the archive'

Then I have tried to make reference with WsecondorFF reference, but get an error too:

$ python ~/bin/WisecondorFF/src/main.py reference -i npz/*.npz -o ref_50kb.npz
Traceback (most recent call last):

I have tried to set RC_CLIP_ABS lower, but it doesn't help.

This is one of my npz
sample_1.zip

For aligning I use bwa-mem2
