GetProteinsAPI

From SPCTools

GetProteins is a CGI script which allows users to query the peptide atlas for one or more proteins of interest.

GetProteins offers a number of filters and options that are not easily set by external websites, so the most common usage is to 
specify a set of proteins and let the user define the other parameters and run the script. That said, the example query below 
provides enough information for the script to automatically run:

This has the following parts:
