I would like to get the current list of stringdb's protein-protein interactions which are supported by experimental evidence (e.g. Y2H), but I have not found an explanation of what the values in their tables are, so I don't know how to filter it.

The file which I believe has the info I am after is: 3702.protein.physical.links.full.v12.0.txt From: https://string-db.org/cgi/download?sessionId=bGUF6uTOzBgh&species_text=Arabidopsis+thaliana

Here are the first two lines from the file:

protein1 protein2 homology experiments experiments_transferred database database_transferred textmining textmining_transferred combined_score
3702.A0A0A7EPL0 3702.Q8LGF7 0 0 118 0 115 0 109 243

My guess is the 'experiments' or 'experiments_transferred' have the relevant information, but I don't know. The values are integers up to the 900s.

Does anyone know how to find interactors with experimental evidence from stringdb?
