Background
The MetaboMate package is the result of my PhD studies and PostDoc time at Imperial College London, where I performed metabolic analysis of urine and plasma samples using Bruker IVDr methods. MetaboMate provides R-tools covering the NMR data analaysis pipeline, including data import, pre-processing and qunatitative comparison using multivariate statistical techniques. All scripts were developed by myself (Torben Kimhofer) and improved over the years. Please feel free to get in touch with me for any queries (torben.kimhofer@murdoch.edu.au).
The MetaboMate project is discontinued from August 2020 onwards
The trend of using larger study cohorts in the field of metabolomics has motivated me to develop a follow-up package: metabom8. This successor package speeds up computation times and the improvement in run-time is achieved by implementing key functions in C++ using the Rcpp package. This means that the MetaboMate project is discontinued and not any longer supported from August 2020 onwards. The new time-improved package (metabom8) differs in R object definitions and also includes additional functionalities for improved (and fast) statistical model building, metabolite identification and data visualisation. metabom8 will be linked to this website and released in due time. -TK
The MetaboMate R toolbox covers all basic data pre-processing and analysis steps, including:
Statistical model interpretation is supported by aestethically pleasing visualisations using ggplot2.
The provided functions to perform statistics (PCA nd O-PLS) can also be applied to mass spectrometry data.
All functions are fully documented, assessible with the help()
function in the R console.
