MERS Lipidomics Data
There are many datasets from the following publications
The raw lipidomics data as a start can be found in MassIVE:
- Primary human airway epithelial cells lipidome response to an icMERS coronavirus MHAE003 - MSV000083535
- Primary human airway epithelial cells lipidome response to an icMERS coronavirus - MSV000083534
- Primary human airway epithelial cells lipidome response to an icMERS coronavirus - MSV000083533
These data from Thomas O. Metz's Lab from PNNL are time course studies of the lipidome of the airway epitheleal tissue.
We have compiled the metadata from the data here.

This API data is a tall tabular csv file with feature and sample metadata pulled into it. It is readily plotable in tools like ggplot2 (R) and plotnine (python). You can read it into your software in a single line:
pd.read_csv("https://proteomics3.ucsd.edu/ProteoSAFe/DownloadResultFile?task=3ed2ee9297ed47f09b42825370895ee9&file=feature_statistics/data_long.csv")
Preliminary Results
Positive Ionization Results - sorted by p-value between mock and MERS

Data Processing Methods
We aim to imploy the following analysis pipeline:
- Feature Finding with MZmine2 in GNPS - Produces peak integration from data
- Feature Based Molecular Networking in GNPS - Produces Molecular network and spectral library matches - machine readable quantitative data
- Statistical Analysis and exploration via Jupyter Notebooks
MERS GC Data
There are many datasets from the following publications
The raw GC Metabolomics data as a start can be found in MassIVE - Primary human airway epithelial cells metabolome response to an icMERS coronavirus
We have compiled the metadata from the data here.
