Hi All,

I couldn't find an answer to this question elsewhere and will appreciate any comment.

In the STRING PPI web site (https://string-db.org/cgi/info?sessionId=bUc75bXGNJId&footer_active_subpage=scores) it is said that: "All scores rank from 0 to 1, with 1 being the highest possible confidence. A score of 0.5 would indicate that roughly every second interaction might be erroneous (i.e., a false positive)."

However, when I download the data, the values are in the range 0-999:

protein1 protein2 neighborhood fusion cooccurence coexpression experimental database textmining combined_score
10090.ENSMUSP00000000001 10090.ENSMUSP00000027991 0 0 0 56 594 500 492 889
10090.ENSMUSP00000000001 10090.ENSMUSP00000137332 0 0 0 0 0 0 163 163

Do these integer values need to be divided by 1000 to get the confidence scores? I mean, does 889 imply 0.889 confidence?
