Python packaging for CPTAC data

bioinformatics cancer proteomics genomics open science open data
pip install cptac==0.6.5



This project is intended to facilitate accessing and interacting with cancer data from the National Cancer Institute CPTAC consortium, which characterizes and studies the proteogenomic landscape of tumors. These cancer studies are downloadable via our Python package as native dataframe objects and can therefore be integrated very quickly and easily with other Python-based data analysis tools. Follow our walkthrough tutorials for a demonstration of ways to use our system.

Our package is publicly available on the Python Package Index (PyPI). Setup instructions can be found in docs/ The quick answer is that this Python package is installed via pip and then is available to all your python software. At a command line enter the following:

pip install cptac

Documentation and Tutorials

All documentation for the project is contained in the docs/ folder. Documentation comes in two flavors: 1 - tutorials which are written to explain the data formats and conventions, 2 - use cases which are written to demonstrate exploring the data for biological discovery. All documentation is written in Python using the interactive Jupyter notebooks. If you are unfamiliar with Jupyter, follow the instructions given at You will then be able to run our tutorials as interactive, exploratory data analyses.


This package is intended to run on Python 3.6 or greater with pandas version 0.25.0 or greater. In the tutorials, we use seaborn 0.9.0 for data visualization.


This package contains document which describes the license for use. Please note the difference between the license as it applies to code versus data.
