Detailed Description

Calculates a consensus from multiple ID runs based on the ranks of the search hits.

Parameters of this class are:

Name	Type	Default	Restrictions	Description
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	0.0	min: 0.0 max: 1.0	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'?
filter:keep_old_scores	string	false	true, false	if set, keeps the original scores as user params

Note:

• If a section name is documented, the documentation is displayed as tooltip.
• Advanced parameter names are italic.
