get_peptide_sequence: Get peptide sequence based on the position

In HaDeX2: Analysis and Visualisation of Hydrogen/Deuterium Exchange Mass Spectrometry Data

Get peptide sequence based on the position

Description

Gets the peptide sequence based on selected parameters (start and end position, modification).

Usage

get_peptide_sequence(
  dat,
  protein = dat[["Protein"]][1],
  start,
  end,
  modification = FALSE
)

Arguments

dat	any data frame that contains following information: protein, sequence, start, end, modification.
protein	chosen protein.
start	start position of the peptide of interest.
end	end position of the peptide of interest.
modification	logical value to indicate if peptide of interest has modification or not.

Details

Function returns peptide sequence for selected parameters. Peptide sequence is often required to properly identify peptide of interest, and to avoid mistakes sequence is returned by the function. Moreover, function uses the modification value to select peptide sequence.

Value

a character value.
