Groups corresponding isotope-labeled features in a feature map.

(or another feature detection algorithm)

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.

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)

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
