[Version: Any] Duplicate proteins crash MS Annika

[michabirklbauer]

If multiple fasta files are selected for search in MS Annika, users have to make sure that they don't overlap - so do not contain the same protein twice (or more often). Duplicate proteins may lead to a crash in MS Annika as Proteome Discoverer enforces that proteins must be unique. A good practice is to merge fasta files beforehand (so pasting all sequences into one fasta file) and only use one fasta file for search in MS Annika, as Proteome Discoverer makes sure that each fasta file only contains unique proteins.
