Detailed Description

A superimposer that uses a voting scheme, also known as pose clustering, to find a good shift transformation.

This algorithm works on two consensus maps. It computes an shift transformation that maps the elements of second map as near as possible to the elements in the first map.

The voting scheme hashes shift transformations between features in map one and features in map two. Each such pair defines a (potential) "pose" of the second map relative to the first. Then it finds a cluster in the parameter space of these poses. The shift transformation is then computed from this cluster of potential poses, hence the name pose clustering.

Parameters of this class are:

Name	Type	Default	Restrictions	Description
mz_pair_max_distance	float	0.5	min: 0.0	Maximum of m/z deviation of corresponding elements in different maps. This condition applies to the pairs considered in hashing.
num_used_points	int	2000	min: -1	Maximum number of elements considered in each map (selected by intensity). Use this to reduce the running time and to disregard weak signals during alignment. For using all points, set this to -1.
shift_bucket_size	float	3.0	min: 0.0	The shift of the retention time interval is being hashed into buckets of this size during pose clustering. A good choice for this would be about the time between consecutive MS scans.
max_shift	float	1000.0	min: 0.0	Maximal shift which is considered during histogramming. This applies for both directions.
dump_buckets	string			[DEBUG] If non-empty, base filename where hash table buckets will be dumped to. A serial number for each invocation will be appended automatically.
dump_pairs	string			[DEBUG] If non-empty, base filename where the individual hashed pairs will be dumped to (large!). A serial number for each invocation will be appended automatically.

Member Function Documentation

◆ create()

Returns an instance of this class.

◆ getProductName()

inlinestatic

Returns the name of this module.

◆ run()

overridevirtual

Estimates the transformation and fills the given mapping function. (Has a precondition!)

Note: Exactly two input maps must be given.

Precondition: For performance reasons, we trust that (the equivalent of:) maps[0].updateRanges(); maps[1].updateRanges(); has been done before calling this. You have been warned!

Exceptions

IllegalArgument is thrown if the input maps are invalid.

Implements BaseSuperimposer.
