Description of the bug

Hi,

I'm running into this error:

20:08:02.464 [ERROR] thread exception: java.lang.NullPointerException: Cannot read field "CopyNumber" because "cnStartPrevData" is null

I'm running oncoanalyser v2.2.0 with a single tumor sample. Using as parameters:
mode: 'wgts'
genome: 'GRCh37_hmf'

Any ideas of what could be wrong?

Thanks in advance for the help!
