Add a column describing the position(s) of the peptide sequence with respect to the protein

Identify the position(s) of the peptide sequence in the protein. Where a sequence has multiple master proteins, the peptide position is undefined (NA).

add_peptide_positions(
  obj,
  proteome_fasta,
  master_protein_col = "Master.Protein.Accessions"
)

Arguments

obj

data.frame with PD output at PSM/peptide level

proteome_fasta

character Filepath for proteome fasta

master_protein_col

character Column name for master protein

Value

data.frame
