Hi everyone,

I have mass spec peptide data. A simple example is shown below.

pep_sequence   start   end   protein_id
ACKJKAC        2       8     AT5G0030
ALLKDK         30      35    AT5G0030
AKLJHLLL       200     207   AT5G0030

I want to draw a graph with each peptide mapped onto the protein (like RNA-seq read mapping graph). Could anyone provide answers (actually I have thousands of peptides, so probably need to use R for batch running or implement R inside perl script). I will be much appreciated for your kind help! THANKS.
