## MTBLS79: Direct infusion mass spectrometry metabolomics dataset: a benchmark for data processing and quality control

### Description

Direct-infusion mass spectrometry (DIMS) metabolomics is an important approach for characterising molecular responses of organisms to disease, drugs and the environment. Increasingly large-scale metabolomics studies are being conducted, necessitating improvements in both bioanalytical and computational workflows to maintain data quality. This dataset represents a systematic evaluation of the reproducibility of a multi-batch DIMS metabolomics study of cardiac tissue extracts. It comprises of twenty biological samples (cow vs. sheep) that were analysed repeatedly, in 8 batches across 7 days, together with a concurrent set of quality control (QC) samples. Data are presented from each step of the workflow and are available in MetaboLights (https://www.ebi.ac.uk/metabolights/MTBLS79)

### Usage

    MTBLS79_DatasetExperiment(filtered = FALSE)

### Arguments

`filtered` | TRUE to load data with quality control filters already applied, or FALSE to load the unfiltered data. Default is FALSE. The raw data is available from (https://www.ebi.ac.uk/metabolights/MTBLS79) and as an R dataset in the `pmp` package, available on Bioconductor.

### Value

DatasetExperiment object

### Examples

    D = MTBLS79_DatasetExperiment()
