**What it does**

The mapping is based on retention times and mass-to-charge values. Roughly, a peptide identification is assigned to a (consensus) feature if its position lies within the boundaries of the feature or close enough to the feature centroid. Peptide identifications that don't match anywhere are still recorded in the resulting map, as "unassigned peptides". Protein identifications are annotated to the whole map, i.e. not to any particular (consensus) feature.

In all cases, tolerance in RT and m/z dimension is applied according to the parameters rt_tolerance and mz_tolerance. Tolerance is understood as "plus or minus x", so the matching range is actually increased by twice the tolerance value.

If several features or consensus features overlap the position of a peptide identification (taking the allowed tolerances into account), the identification is annotated to all of them.

Annotation of feature maps (featureXML input):
If all features have at least one convex hull, peptide positions are matched against the bounding boxes of the convex hulls (of individual mass traces, if available) by default. If not, the positions of the feature centroids are used. The respective coordinates of the centroids are also used for matching (in place of the corresponding ranges from the bounding boxes) if feature:use_centroid_rt or feature:use_centroid_mz are true.

Annotation of consensus maps (consensusXML input):
Peptide positions are always matched against centroid positions. By default, the consensus centroids are used. However, if consensusfeature:use_subelements is set, the centroids of sub-features are considered instead. In this case, a peptide identification is mapped to a consensus feature if any of its sub-features matches.
