Receiving an "Invalid Character Error" when using OMSSAAdapter

Okay. Neither my supervisor nor I have worked with KNIME/OpenMS before, so I apologize for the naive questions and hand-holding I’m needing.

He said I should be using OpenMS for MS Only Full Scan data for pairwise comparisons of our data, am I able to do this in OpenMS? Or do you happen to know of any papers/writeups of doing something similar to this?

I see from this issue that OMSSAAdapter is not really supported anymore, and should be moved to CometAdapter or MSGFPlusAdapter.

I appreciate your time in helping me on this
