Longitudinal VOCs profiling by direct-injection mass spectrometry reveals the interaction between the gut microbiota and dietary fibers in-vitro

This dataset contains supplementary data files used in the analysis of volatile organic compounds (VOCs) released over time from gut microbiota related to three type of fermentations and a control: basal medium, inulin, oat bran and sterile medium (Control). The files are organized as follows:

ClusterMap: Contains hierarchical clustering results and heatmap visualizations of VOC profiles across different sample types and time points, generated using Seaborn’s clustermap function.

Concentration Time Battery Plots: Time-course plots displaying VOC concentrations over various fermentation stages for each substrate, alll the observed temporal changes in VOC profiles.

Datasets: The raw and processed VOC data collected using Proton Transfer Reaction Mass Spectrometry (PTR-MS) for each substrate, including replicate measurements.

DIABLO: Data files and scripts related to the DIABLO (Data Integration Analysis for Biomarker discovery using Latent cOmponents) framework used to integrate VOCs measurments across PTR-MS and GC-MS platforms

RM-ASCA: Results from the RM-ASCA (Repeated Measures Analysis of Variance-Simultaneous Component Analysis) performed to identify significant VOC variations across time points and substrates.
