AccurateMassSearch

Match MS signals to molecules from a database by mass.

Web Documentation for AccurateMassSearch

Options

version
Version of the tool that generated this parameters file.
log
Name of log file (created only when specified)
debug
Sets the debug level
threads
Sets the number of threads allowed to be used by the TOPP tool
no_progress
Disables progress logging to command line
force
Overrides tool-specific checks
test
Enables the test mode (needed for internal use only)
mass_error_value
Tolerance allowed for accurate mass search.
mass_error_unit
Unit of mass error (ppm or Da)
ionization_mode
Positive or negative ionization mode? If 'auto' is used, the first feature of the input map must contain the meta-value 'scan_polarity'. If its missing, the tool will exit with error.
isotopic_similarity
Computes a similarity score for each hit (only if the feature exhibits at least two isotopic mass traces).
use_feature_adducts
Whether to filter AMS candidates mismatching available feature adduct annotation.
keep_unidentified_masses
Keep features that did not yield any DB hit.
id_format
Use legacy (ProteinID/PeptideID based storage of metabolomics data) with mzTab-v1.0.0 as output format or novel Identification Data (ID) with mzTab-v2.0.0-M as output format (ID and its MzTab-M output is currently only support for featureXML files).
exportIsotopeIntensities
[featureXML input only] Export column with available isotope trace intensities (opt_global_MTint)

Input Ports

Icon
featureXML or consensusXML file [featureXML,consensusXML]
Icon
This file contains the list of potential positive adducts that will be looked for in the database. Edit the list if you wish to exclude/include adducts. By default CHEMISTRY/PositiveAdducts.tsv in OpenMS/share is used. [tsv]
Icon
This file contains the list of potential negative adducts that will be looked for in the database. Edit the list if you wish to exclude/include adducts. By default CHEMISTRY/NegativeAdducts.tsv in OpenMS/share is used. [tsv]
Icon
Database input file(s), containing three tab-separated columns of mass, formula, identifier. If 'mass' is 0, it is re-computed from the molecular sum formula. By default CHEMISTRY/HMDBMappingFile.tsv in OpenMS/share is used! If empty, the default will be used. [tsv]
Icon
Database input file(s), containing four tab-separated columns of identifier, name, SMILES, INCHI.The identifier should match with mapping file. SMILES and INCHI are reported in the output, but not used otherwise. By default CHEMISTRY/HMDB2StructMapping.tsv in OpenMS/share is used! If empty, the default will be used. [tsv]

Output Ports

Icon
mzTab file [mzTab]
Icon
A copy of the input file, annotated with matching hits from the database. [featureXML,consensusXML,oms]

AccurateMassSearch Std Output
The text sent to standard out during the execution of AccurateMassSearch.
AccurateMassSearch Error Output
The text sent to standard error during the execution of AccurateMassSearch. (If it appears in gray, it's the output of a previously failing run which is preserved for your trouble shooting.)
