cBioPortal provides clinical data from a number of different cancer studies. The clinical data from the studies is conveniently organized in a tabular format, however the data available varies between different studies. The variation in data makes it difficult to directly compare all of the different studies. The aim of this project is to standardize the data currently available and to propose certain standards for the data added to cBioPortal from future studies. Standardized data will allow for users to more easily work with the data provided by cBioPortal.
