I’m sorry about this but I'm still unable to download the files.
Yesterday I tried with all the ideas I had with no success.
> entity <- synGet(id='syn5758204', downloadLocation='~/Researchs/germline')
Error in value[[3L]](cond) :
get() missing 1 required positional argument: ‘entity'
> entity <- synGet("syn5758204", downloadLocation="~/Researchs/germline")
Error in value[[3L]](cond) : EOF when reading a line
Unfortunately I haven’t found more info about the download function ( http://docs.synapse.org/articles/downloading_data.html) to figured out what is missing
