Default for runSerotyping coverage not being set correctly

[AdmiralenOla]

Dear seroba team,

I have run into an issue where serotyping won't run unless I explicitly set coverage.

root@d2d570a8775d:/# seroba runSerotyping seroba/database/ data/testsample_1.fastq.gz data/testsample_2.fastq.gz data/TESTcontainer
Traceback (most recent call last):
  File "/usr/local/bin/seroba", line 4, in <module>
    __import__('pkg_resources').run_script('seroba==1.0.2', 'seroba')
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 650, in run_script
    self.require(requires)[0].run_script(script_name, ns)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 1453, in run_script

TypeError: unsupported operand type(s) for /: 'NoneType' and 'float'

It seems like a default value for cov is not being set? I can get it to run by explicitly specifying coverage:

root@d2d570a8775d:/# seroba runSerotyping --coverage 20 /seroba/database/ /data/ERR1438805_1.fastq.gz /data/ERR1438805_2.fastq.gz /data/TESTcontainer

I am using the latest docker container from sangerpathogens/seroba (b4f4e60ee092)

Even I am facing the same error. I am running singularity container on centos7 shared compute resources
