any tool yielding output in mzML, featureXML or consensusXML format | any tool that profits on reduced input |
With this tool it is possible to extract m/z, retention time and intensity ranges from an input file and to write all data that lies within the given ranges to an output file.
Depending on the input file type, additional specific operations are possible:
The priority of the id-flags is (decreasing order): remove_annotated_features / remove_unannotated_features -> remove_clashes -> keep_best_score_id -> sequences_whitelist / accessions_whitelist
MS2 and higher spectra can be filtered according to precursor m/z (see 'peak_options:pc_mz_range'). This flag can be combined with 'rt' range to filter precursors by RT and m/z. If you want to extract an MS1 region with untouched MS2 spectra included, you will need to split the dataset by MS level, then use the 'mz' option for MS1 data and 'peak_options:pc_mz_range' for MS2 data. Afterwards merge the two files again. RT can be filtered at any step.
The command line parameters of this tool are:
FileFilter -- Extracts or manipulates portions of data from peak, feature or consensus-feature files. Version: 2.3.0 Jan 9 2018, 17:46:23, Revision: 38ae115 Usage: FileFilter <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>* Input file (valid formats: 'mzML', 'featureXML', 'consensusXML') -in_type <type> Input file type -- default: determined from file extension or content (valid: 'mzML', 'featureXML', 'consensusXML') -out <file>* Output file (valid formats: 'mzML', 'featureXML', 'consensusXML') -out_type <type> Output file type -- default: determined from file extension or content (valid: 'mzML', 'featureXML', 'consensusXML') -rt [min]:[max] Retention time range to extract (default: ':') -mz [min]:[max] M/z range to extract (applies to ALL ms levels!) (default: ':') -int [min]:[max] Intensity range to extract (default: ':') -sort Sorts the output according to RT and m/z. Peak data options: -peak_options:sn <s/n ratio> Write peaks with S/N > 'sn' values only (default: '0') -peak_options:rm_pc_charge i j ... Remove MS(2) spectra with these precursor charges.
