What It Does
------------
**Disclaimer** this tool needs a peptide database to query against, if you did not create one yet you can do so by using the `PeptideDB <https://csbiology.github.io/ProteomIQon/tools/PeptideDB.html>`_ tool.

Given raw a MS run in the mzite format, this tool iterates accross all recorded MS/MS scans and determines the charge state of precursor ions which were selected for fragmentation. 
With this it is possible to query the peptide data base for every precursor ion mass +/- a tolerance (which defines the so called 'search space') and retrieve peptides that are 
theoretical candidates for a match. For each of the peptide candidates we create an theoretical spectrum in silico and compare it to the measured MS/MS scan.

            :width: 768pt
            :height: 563pt

To measure similarity we use our own implementations of three established search enginge scores: SEQUEST, Andromeda and XTandem. 
The search space is extended by so called decoys. Decoys are reversed counterparts of peptides within the search space and allow 
us to assign a false discovery rate to each scored peptide using the `PSMStatistics <https://csbiology.github.io/ProteomIQon/tools/PSMStatistics.html>`_ tool.
