subsetting peptide sequence #9

Dear MVP developer team, Thank you very much for this great software. I am excited to test it for our HLA peptidome data. The published reports look fantastic. I don't think it is possible to download/export data from the HTML report (?) For example, I am interested to get the sequences of the "strong binders" peptides for one allele. What is the best way to do it? Thanks

Thank you for your interest in the software! You are correct that the HTML report itself doesn't contain the binding predictions. That is a good idea, though, so I might look into implementing it. However, when you run the tool, you get an option to save the predictions (using the "Link to analysis archive"):

The "analysis archive" contains netMHCpan predictions for each sample:

To find predictions for a specific allele, you can filter by the "Allele" column, or to find the predictions for a specific peptide you can filter by the "Peptide" column. The "Binder" column is defined by the EL_rank. If it is greater than 2.0 it is a non-binder, if it is less than or equal to 2.0 it is a weak-binder, and if it is less than or equal to 0.5 it is a strong binder.

I hope that is helpful! Let me know if you need anything else. As I mentioned, I will look into making these predictions available through the HTML report. That is a good idea.

Best wishes, Kevin
