# PiperNET data

Data for PiperNET, a multi-*omics* platform for elucidating the biosynthetic origin of plant specialized metabolites.
It holds LC-MS metabolomics and RNA-Seq transcriptomics data from several *Piper* species and tissues, with biological replicates.
Code and pipeline: [github.com/titodamiani/PiperNET](https://github.com/titodamiani/PiperNET).

## Download
With the [`hf` command line tool](https://huggingface.co/docs/huggingface_hub/guides/cli):
```bash
hf download titodamiani/PiperNET --repo-type dataset --local-dir data
```
To download one folder only, add `--include`, for example `--include "processed/*"`.
To run the code on this data, follow the installation steps in the [code repository](https://github.com/titodamiani/PiperNET).
