This tool provides an algorithm for grouping corresponding features in isotope-labeled experiments. For more details and algorithm-specific parameters (set in the ini file) see "Detailed Description" in the algorithm documentation.

FeatureLinkerLabeled takes one feature map (featureXML file) and stores the corresponding features in a consensus map (consensusXML file). Feature maps can be created from MS experiments (peak data) using one of the FeatureFinder TOPP tools.

The command line parameters of this tool are:

FeatureLinkerLabeled -- Groups corresponding isotope-labeled features in a feature map.
Version: 1.10.0 Mar  7 2013, 08:30:22, Revision: unknown

Usage:
  FeatureLinkerLabeled <options>

This tool has algoritm parameters which can only be used via an INI file and are not accessible from the command line!

Options (mandatory options marked with '*'):
  -in <file>*        Input file (valid formats: 'featureXML')
  -out <file>*       Output file (valid formats: 'consensusXML')
                     
Common TOPP options:
  -ini <file>        Use the given TOPP INI file
  -threads <n>       Sets the number of threads allowed to be used by the TOPP tool (default: '1')
  -write_ini <file>  Writes the default configuration file
  --help             Shows options
  --helphelp         Shows all options (including advanced)

The following configuration subsections are valid:
 - algorithm   Algorithm parameters section

You can write an example INI file using the '-write_ini' option.
Documentation of subsection parameters can be found in the
doxygen documentation or the INIFileEditor.
Have a look at OpenMS documentation for more information.

rt_estimatetrue If 'true' the optimal RT pair distance and deviation are estimated by fitting a gaussian distribution to the histogram of pair distance. Note that this works only datasets with a significant amount of pairs! If 'false' the parameters 'rt_pair_dist', 'rt_dev_low' and 'rt_dev_high' define the optimal distance.true,false

rt_pair_dist-20 optimal pair distance in RT [sec] from light to heavy feature

rt_dev_low15 maximum allowed deviation below optimal retention time distance0:∞

rt_dev_high15 maximum allowed deviation above optimal retention time distance0:∞

mz_pair_dists[4] optimal pair distances in m/z [Th] for features with charge +1 (adapted to +2, +3, .. by division through charge)

mz_dev0.05 maximum allowed deviation from optimal m/z distance
0:∞

mrmfalse this option should be used if the features correspond mrm chromatograms (additionally the precursor is taken into account)true,false
