Remove features which are assigned to a protein with too few supporting features in total

For summarisation of PSM or peptide to protein, we need a minimum number of finite values per protein per sample.

Usage

filter_features_per_protein(
  obj,
  min_features,
  master_protein_col = "Master.Protein.Accessions",
  plot = FALSE
)

Arguments

obj

SummarizedExperiment with PSM or peptide-level quantification

min_features

numeric Threshold for minimum features per protein

master_protein_col

character Column name for master protein

plot

Set TRUE to plot histogram of features per protein per sample

Value

SummarizedExperiment
