Protein coverage calculation

[apsteinberg]

Hi all,

I had a quick question regarding how the calculation of protein coverage is performed in the protein.tsv report. I was trying to compute protein coverage by using the results that are in the peptide.tsv -- basically, I was taking the Protein Start and Protein End positions listed for each peptide related to a given protein in the peptide.tsv file, and using these to compute protein coverage. I am finding there is a slight discrepancy between the values. Does the protein coverage listed in the protein.tsv report include some additional peptides?

Thanks, Asher
