Description of the bug

@jpfeuffer @timosachsenberg @daichengxin I found one dataset that we search using msgf, here the command:

However in the file output I found the following id:

What could be the problem, this also happens for comet.

according to this comment in our adapter it is only used if no charge is annotated in the mzML

@jpfeuffer @timosachsenberg would it make sense to add a parameter to filter the psms in that charge range?

[timosachsenberg]

good question.
I think these high charge peptides are potentially interesting so one could argue that one wants them to be reported.
On the other hand you get more defined / consistent results without filtering.
I would probably keep them by default but I could add an optional filter if we decide that we want to filter them
