Usage:
AssayGeneratorMetaboSirius <options>
Options (mandatory options marked with '*'):
-in <directory>* SIRIUS project directory
-in_compoundinfo <file>* Compound info table (.tsv file) (valid formats: 'tsv')
-out <file>* Assay library output file (valid formats: 'tsv', 'traML', 'pqp'
)
-ambiguity_resolution_mz_tolerance <num> Mz tolerance for the resolution of identification ambiguity
over multiple files (default: '10.0')
-ambiguity_resolution_rt_tolerance <num> RT tolerance in seconds for the resolution of identification
ambiguity over multiple files (default: '10.0')
-total_occurrence_filter <num> Filter compound based on total occurrence in analysed samples
(default: '0.1') (min: '0.0' max: '1.0')
-fragment_annotation_score_threshold <num> Filters annotations based on the explained intensity of the
peaks in a spectrum (default: '0.8') (min: '0.0' max: '1.0')
-method <choice> Spectrum with the highest precursor intensity or a consensus
spectrum is used for assay library construction (if no fragment
annotation is used). (default: 'highest_intensity') (valid:
'highest_intensity', 'consensus_spectrum')
-use_exact_mass Use exact mass for precursor and fragment annotations
-exclude_ms2_precursor Excludes precursor in ms2 from transition list
-use_known_unknowns Use features without identification information
-min_transitions <int> Minimal number of transitions (default: '3')
-max_transitions <int> Maximal number of transitions (default: '6')
-transition_threshold <num> Further transitions need at least x% of the maximum intensity
(default 5%) (default: '5.0')
-decoy_generation Decoys will be generated using the fragmentation tree re-rootin
g approach. This option does only work in combination with the
fragment annotation via Sirius.
-decoy_generation_method <choice> Uses different methods for decoy generation. Basis for the meth
od is the fragmentation-tree re-rooting approach ('original').
This approach can be extended by using 'resolve_overlap', which
will resolve overlapping target/decoy fragments by adding -CH2
mass to the overlapping decoy fragments. 'generate_missing_dec
oys' will add a -CH2 mass shift to the target fragments and
use them as decoys if fragmentation-tree re-rooting failed.
'Both' combines the extended methods (resolve_overlap, generate
_missing_decoys). (default: 'original') (valid: 'original',
'resolve_overlap', 'generate_missing_decoys', 'both')
-decoy_resolution_mz_tolerance <num> Mz tolerance for the resolution of overlapping m/z values for
targets and decoys of one compound. (default: '10.0')
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)
