calcMW: Calculate molecular weight

Description Usage Arguments Value Author(s) Examples

Description

Function to calculate molecular weight of a fragment generated by the MassCLEAVE assay for either the T or C cleavage reactions

Usage

1
calcMW(sequence, extra = c("5OH", "5PPP-3P", "5PPP-3OH"), adduct = c("", "Na", "K"), rxn = c("T", "C"))

Arguments

sequence

Nucleotide sequence input

extra

One of "5OH" (default), "5PPP-3P", or "5PPP-3OH" describing 5' and/or 3' modifications of the fragment

adduct

One of 'Na', 'K', or ” (default) specifying whether or not the molecular weight should be calculated for a salt adduct

rxn

One of 'T' or 'C' indicating which cleavage reaction is employed to generate the fragment

Value

Returns a numerical output corresponding to the molecular weight (in Da) of sequence input. Note that the output may actually represent multiple molecular weights if/whenever the input sequence contains one or more degenerate bases (e.g. R or Y).
