Installation

# install susiepca dependency
uv pip install susiepca@git+https://github.com/mancusolab/susiepca.git@main

# install perturbvi
uv pip install perturbvi

# help
perturbvi --help

Get Started with perturbvi

Perform inference using SuSiE PCA to find the regulatory modules from CRISPR perturbation data

perturbvi <matrix> <guide> <z_dim> <l_dim> <tau> -o=<out_dir> --verbose

Arguments

• matrix: Path to the experiment CSV file.
• guide: Path to the guide CSV file.
• z_dim: Number of latent factors, Z dim (12).
• l_dim: Number of single effects, L dim (400).
• tau: Residual precision, Tau (800).
• out_dir: Specifies the output directory path.
• --verbose: For logging (Optional).

Example Usage

perturbvi luhmes_exp.csv luhmes_G.csv 12 400 800 -o=results --verbose

This will save the all the output files (including the parameter file params.pkl) into the results folder, which can be used for the downstream tasks.

Notes

• perturbvi uses JAX with Just In Time compilation to achieve high-speed computation. However, there are some issues for JAX with Mac M1 chip. To solve this, users need to initiate conda using miniforge, and then install perturbvi using pip in the desired environment.
