There are two different environments for testing and learning how to use OpenCGA, they are called opencga-demo and and opencga-test, see details in this table:
Project: exomes_grch37 (studies corpasome and ceph_trio)
As you can see both environments aim to contain the same datasets organised in the same Project and Study structure with the same IDs and names, this will make much easier to test scripts and functionality to the new development version. All tutorials are expected to use opencga-demo environment whenever is possible.
