Accurate mass search against a database (usually HMDB). For details see AccurateMassSearchEngine.
The command line parameters of this tool are:
AccurateMassSearch -- Match MS signals to molecules from a database by mass. Version: 2.3.0 Jan 9 2018, 17:46:23, Revision: 38ae115 Usage: AccurateMassSearch <options> This tool has algorithm parameters that are not shown here! Please check the ini file for a detailed descript ion 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: 'tsv') -out_annotation <file> A copy of the input file, annotated with matching hits from the database. (valid formats: 'featureXML', 'consensusXML') 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/H MDB2StructMapping.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! If empty, the default will be 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! If empty, the default will be used. (valid formats: 'tsv') Common UTIL 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 the OpenMS documentation for more information.
