I've created synapse entities for the new GRCh38 version of the human genome and have pointed them to the FTP download link at Ensembl. It would sure be nice if I could "syn.get" them from the python client.
See https://www.synapse.org/#!Synapse:syn2572799 for an example.
Covered in same work as ftp upload for TCGA?
