deciphering Dat summaries

Reported by jtprince | February 10th, 2009 @ 01:35 PM

some notes on deciphering the Dat summary section [work in progress]

XX is probably unknowable (based on not seeing the information in the csv or xml export)
?? is currently unknown

So, here is a sample line (hit 14, from query 2 (??)):

h14_q2=0,936.455246,0.001202,53,61,4.00,GYASPDLSK,16,00000000000,22.56,1,0002001000000000000,0,0,1671.400000

0=??
1=Mr(expt)
2=deltamass
3=peptide_start
4=peptide_end
5=XX
6=Peptide (the sequence)
7=??
8=PeptideScore
9=Rank
10=??
11=??
12=??
13=??

Note that peptide start and end have to be adjusted for Methionines!
