Options

version
Version of the tool that generated this parameters file.
precursor_mass_tolerance
Precursor monoisotopic mass tolerance.
precursor_mass_tolerance_unit
Unit to be used for precursor mass tolerance.
precursor_mass_tolerance_avg
If this flag is set, the average mass is used in the precursor mass tolerance.
fragment_mass_tolerance
Fragment mass error in Dalton
fragment_mass_tolerance_unit
Unit to be used for fragment mass tolerance.
fixed_modifications
Fixed modifications, specified using Unimod (www.unimod.org) terms, e.g. 'Carbamidomethyl (C)' or 'Oxidation (M)'
variable_modifications
Variable modifications, specified using Unimod (www.unimod.org) terms, e.g. 'Carbamidomethyl (C)' or 'Oxidation (M)'
NumChargeStates
The number of charge states that MyriMatch will handle during all stages of the program.
TicCutoffPercentage
Noise peaks are filtered out by sorting the original peaks in descending order of intensity, and then picking peaks from that list until the cumulative ion current of the picked peaks divided by the total ion current (TIC) is greater than or equal to this parameter.
MaxDynamicMods
This parameter sets the maximum number of modified residues that may be in any candidate sequence.
MaxResultRank
This parameter sets the maximum rank of peptide-spectrum-matches to report for each spectrum.
CleavageRules
This parameter allows the user to control the way peptides are generated from the protein database. For more details, see http://www.ebi.ac.uk/ontology-lookup/browse.do?ontName=MS&termId=MS:1001045&termName=cleavage%20agent%20name .
MinTerminiCleavages
By default, when generating peptides from the protein database, a peptide must start and end at a valid cleavage site. Setting this parameter to 0 or 1 will reduce that requirement, so that neither terminus or only one terminus of the peptide must match one of the cleavage rules specified in the CleavageRules parameter. This parameter is useful to turn a tryptic digest into a semi-tryptic digest.
MaxMissedCleavages
By default, when generating peptides from the protein database, a peptide may contain any number of missed cleavages. A missed cleavage is a site within the peptide that matches one of the cleavage rules (refer to CleavageRules). Settings this parameter to some other number will stop generating peptides from a sequence if it contains more than the specified number of missed cleavages.
MinPeptideMass
When preprocessing the experimental spectra, any spectrum with a precursor mass that is less than the specified mass will be disqualified.
MaxPeptideMass
When preprocessing the experimental spectra, any spectrum with a precursor mass that exceeds the specified mass will be disqualified.
MinPeptideLength
When digesting proteins, any peptide which does not meet or exceed the specified length will be disqualified.
MaxPeptideLength
When digesting proteins, any peptide which exceeds this specified length will be disqualified.
UseSmartPlusThreeModel
When this parameter is set, then for each peptide bond, an internal calculation is done to estimate the basicity of the b and y fragment sequence. The precursors protons are distributed to those ions based on that calculation, with the more basic sequence generally getting more of the protons..
NumIntensityClasses
Before scoring any candidates, experimental spectra have their peaks stratified into the number of intensity classes specified by this parameter.
ClassSizeMultiplier
When stratifying peaks into a specified, fixed number of intensity classes, this parameter controls the size of each class relative to the class above it (where the peaks are more intense).
MonoisotopeAdjustmentSet
This parameter defines a set of isotopes (0 being the instrument-called monoisotope) to try as the monoisotopic precursor m/z. To disable this technique, set the value to '0'.
SpectrumListFilters
Optional set of filters as described in the MyriMatch documentation.
ignoreConfigErrors
Ignore wrong parameter names or values. Use with maximum caution!
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
Overwrite tool specific checks.
test
Enables the test mode (needed for internal use only)
