An algorithm to search for exact mass matches from a spectrum against a database (e.g. HMDB).
Accurate mass search against a database (usually HMDB). For details see AccurateMassSearchEngine.
- Note
- Currently mzIdentML (mzid) is not directly supported as an input/output format of this tool. Convert mzid files to/from idXML using IDFileConverter if necessary.
The command line parameters of this tool are:

Usage:
AccurateMassSearch <options>
This tool has algorithm parameters that are not shown here! Please check the ini file for a detailed description or use the --helphelp option
Options (mandatory options marked with '*'):
-in <file>* FeatureXML or consensusXML file (valid formats: 'featureXML', 'consensusXML')
-out <file>* MzTab file (valid formats: 'mzTab')
-out_annotation <file> A copy of the input file, annotated with matching hits from the database. (valid formats: 'featureXML', 'consensusXML', 'oms')
Database files which contain the identifications:
-db:mapping <file(s)>* 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. (valid formats: 'tsv')
-db:struct <file(s)>* 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. (valid formats: 'tsv')
-positive_adducts <file>* 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. (valid formats: 'tsv')
-negative_adducts <file>* 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. (valid formats: 'tsv')
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:

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.
