Detailed Description

XTandem input file.

This class is able to load/write a X!Tandem configuration file.

These files store parameters within 'note' tags, e.g.,

  <note type="input" label="spectrum, fragment monoisotopic mass error">0.4</note>
	<note type="input" label="output, proteins">yes</note>

Member Function Documentation

convertModificationSet_()

String convertModificationSet_ ( const std::set< ModificationDefinition > &  mods, std::map< String, double > &  affected_origins  ) const

protected

Converts the given set of Modifications into a format compatible to X!Tandem.

The set affected_origins can be used to avoid duplicate modifications, which are not supported in X! Tandem. Currently, a warning message is printed. Also, if a fixed mod is already given, a corresponding variable mods needs to have its delta mass reduced by the fixed modifications mass. This is also done automatically here.

Parameters

mods	The modifications to convert
affected_origins	Set of origins, which were used previously. Will be augmented with the current mods.

An X! Tandem compatible string representation.
