Parse StrucGP Structures

Parse StrucGP-style structure characters into a glyrepr::glycan_structure(). See example below for the structure format.

Usage

parse_strucgp_struc(x, on_failure = "error")

Arguments

x

A character vector of StrucGP-style structure strings. NA values are allowed and will be returned as NA structures.

on_failure

How to handle parsing failures. "error" aborts when a structure cannot be parsed. "na" returns NA at invalid positions.

Value

A glyrepr::glycan_structure() object.

Examples

glycan <- parse_strucgp_struc("A2B2C1D1E2F1fedD1E2edcbB5ba")
print(glycan, verbose = TRUE)
#> <glycan_structure[1]>
#> [1] Hex(??-?)HexNAc(??-?)Hex(??-?)[HexNAc(??-?)Hex(??-?)]Hex(??-?)HexNAc(??-?)[dHex(??-?)]HexNAc(??-
