About

This repository contains scripts for programmatic access to Lichtman Lab datasets hosted by CAVE (Connectome Annotation and Versioning Engine). The scripts are written in Python and use the CAVEClient.

Supported Datasets

Interactive proofreading can be done through this link - also check out the proofreading tutorial.

Getting Started

Local Environment

Setup a virtual environment using virtualenv.

For MacOS or Linux Users

git clone https://github.com/VCG/cave-scripts.git
cd cave-scripts
virtualenv -p python3.9 venv
source venv/bin/activate
pip install -r requirements.txt

For Windows Users

git clone https://github.com/VCG/cave-scripts.git
cd cave-scripts
python -m venv venv
.\venv\Scripts\Activate
pip install -r requirements.txt

Troubleshooting

  • If you receive the error message virtualenv is not recognized, please install virtualenv using pip install virtualenv.

  • When you try to activate the virtualenv with .\venv\Scripts\Activate and you have an error message cannot be loaded because running scripts is disabled on this system., you need to change the execution policy of the Powershell.

    Get-ExecutionPolicy # check this returns Restricted
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
Get-ExecutionPolicy # check this returns RemoteSigned

    Now, you can activate the virtualenv.

Request CAVE permission

Submit this form to request access. We will respond within 24h. If you don't hear back, please email us.

CAVE credentials

Use this script to get your CAVE credentials. This assumes you have been approved in the previous step already.

Limitations / Known Issues

Programmatic access to H01 & Fish 1.0 through CAVE is fairly new. So expect improvements, and please report bugs by opening an issue in the repository.
