rt_delta
and mz_delta
have been renamed to rt_tolerance
and mz_tolerance
. The possible values of the mz_reference
parameter have also been renamed. The default value of mz_tolerance
has been increased from 1 ppm to a more realistic 20 ppm.use_centroids
parameter from previous versions has been split into two parameters, feature:use_centroid_rt
and feature:use_centroid_mz
. In OpenMS 1.6, peptide identifications would be matched only against monoisotopic mass traces of features if mz_reference
was PeptideMass
; otherwise, all mass traces would be used. This implicit behaviour has been abandoned, you can now explicitly control it with the feature:use_centroid_mz
parameter. feature:use_centroid_mz
does not take into account m/z deviations in the monoisotopic mass trace, but this can be compensated by increasing mz_tolerance
. The new implementation should work correctly even if the monoisotopic mass trace itself was not detected.
