In GCalignR: Simple Peak Alignment for Gas-Chromatography Data

Aligned Gas-Chromatography data

Description

This is in example of an aligned gas-chromatography dataset processed with align_chromatograms. The raw data is accessible within this package as peak_data.RData and is comprised of 41 Mother-Pup pairs of Antarctic Fur Seals (Arctocephalus gazella) sampled from two different colonies at Bird Island, South Georgia. In addition two blanks are included.

Format

Object of class "GCalign" including three lists. List "aligned" includes data.frames for all variables present in the raw data ("time" and "area"). The list "heatmap_input" holds data frames with retention times of the input data, linearly adjusted retention times as well as the final output, were peaks are aligned among samples. This file is primarily used in gc_heatmap. The list "Logfile" summarises the alignment process and the data structure before, during and after running align_chromatograms. For a convenient overview use print.GCalign.
