Detailed Description

Calculates a consensus from multiple ID runs based on PEPs and shared ions.

Parameters of this class are:

Name	Type	Default	Restrictions	Description
mass_tolerance	float	0.5	min: 0	Maximum difference between fragment masses (in Da) for fragments to be considered 'shared' between peptides .
min_shared	int	2	min: 1	The minimal number of 'shared' fragments (between two suggested peptides) that is necessary to evaluate the similarity based on shared peak count (SPC).
filter:considered_hits	int	0	min: 0	The number of top hits in each ID run that are considered for consensus scoring ('0' for all hits).
filter:min_support	float	0	min: 0 max: 1	For each peptide hit from an ID run, the fraction of other ID runs that must support that hit (otherwise it is removed).
filter:count_empty	string	false	true, false	Count empty ID runs (i.e. those containing no peptide hit for the current spectrum) when calculating 'min_support'?
