All xcorr are zero

[Viktor Granholm]

Hi group,

I've started using crux 1.37 but ran into problems as all xcorrs in the sqt-files after my sequest-searches turn out to be zero. Here's an example:

S       1374    1374    3       0.0     server  1449.7317       0.00    0.00000000      3970

M       1       1       1449.7212       nan     0       79.219582       8       48      Q.AIDHAVQLSRDEP.S       U

L       fid|6014821|locus|ECBD_1912|

Apart from that, the search worked fine. I used the following parameters:

precursor-window=15

precursor-window-type=ppm

isotopic-mass=mono

fragment-mass=mono

mod=15.994915:M:4

enzyme=no-enzyme

num-decoys-per-target=0

mz-bin-width=0.36

mz-bin-offset=0.11

I saw this for a few different ms2-files, do you have an idea of why this happens? Tell me if you'd need more information.

Thank you,

Viktor
