Swan is a Python library designed for the analysis and visualization of transcriptomes, especially with long-read transcriptomes in mind. Users can add transcriptomes from different datasets and explore distinct splicing and expression patterns across datasets.

Please visit the [Swan repository](https://github.com/mortazavilab/swan_vis) to download and view the source code

Also see the [Swan manuscript repository](https://github.com/fairliereese/swan_paper) for the exact commands used to do the analysis in our [publication](https://academic.oup.com/bioinformatics/advance-article/doi/10.1093/bioinformatics/btaa836/5912931).

Also see our [website](https://freese.gitbook.io/swan/) for in-depth tutorials and documentation

## What can Swan do?

Swan can make informative plots, find differentially expressed genes and transcripts, find isoform-switching genes, and discover novel exon skipping and intron retention events.

## Installation

Swan can be installed directly from PyPi. To install Swan's most recent release, run

`pip install swan_vis`

Alternatively, the most recent commits can be installed by git cloning [the Swan repository](https://github.com/fairliereese/swan_vis), moving to the swan\_vis directory, and running

`pip install .`
