Select annotation rules from the MALDI matrix/reagent profile

Source: R/MZAnnotationEngine.R
MALDIMatrixRules.Rd

Conventional matrices select ordinary ion rules and, where validated, matrix-metabolite adducts. Reactive matrices additionally select covalent product rules. Profiles without a verified universal net transformation are retained in the registry but do not generate speculative mass shifts.

Usage

MALDIMatrixRules(
  maldi_matrix,
  polarity = NULL,
  include_standard = TRUE,
  include_matrix_products = TRUE
)

Arguments

maldi_matrix

Matrix or derivatization reagent name; aliases such as "2,5-DHB", "HCCA", "9-AA", and "FMP-10" are accepted.

polarity

"positive", "negative", or "neutral". If NULL, use the profile default; profiles supporting both modes require an explicit choice.

include_standard

Include the validated ordinary adduct rules.

include_matrix_products

Include validated matrix-adduct or reactive product rules.

Value

A validated adduct/reaction rule data frame accepted by BuildMZAnnotationIndex().
