XCMS / Re: [QUESTION] Package that would filter the "bad gaussian curves" kept by XCMS
I do not know if any package that does so as you describe.
If you want to improve your xcms processing settings, you may test this R package: http://bmcbioinformatics.biomedcentral.com/articles/10.1186/s12859-015-0562-8
Maybe someone else can help you better,
