The CCD Causal Software suite offers easy to use software for causal discovery from large and complex biomedical datasets, applying Bayesan and constraint based algorithms. It includes a web application as well as API’s and a command line version.

To better support you in using the tools as well as for all your questions regarding setting up pipe lines or performing data analyses with our tools we have set up the CCD Helpdesk that can be reached 24/7 via email and daily via phone and chat.

Causal Web

our user-friendly web application for performing causal discovery analysis on big data using large memory servers at the Pittsburgh Supercomputing Center. Use this software if you want to quickly try out a causal discovery algorithm or if you have big data that cannot be analyzed on your local hardware.

The software currently includes:

Causal Command

a Java library and command line implementation of algorithms for performing causal discovery on big data. Use this software if you are interested incorporating analysis via a shell script or in a Java-based program. The ‘Software’ button below leads to a comprehensive repository. Choose the ‘causal-cmd-x.x.x -jar-with-dependencies.jar’ from the downloads list when using this as an executable via the command line or as an API in a Java program.

Tetrad

TETRAD is a desktop java application that can connect to outside super computing resources if neccesary which creates, simulates data from, estimates, tests, predicts with, and searches for causal and statistical models. The aim of the program is to provide sophisticated methods in a friendly interface requiring very little statistical sophistication of the user and no programming knowledge.
