# www.genesys-pgr.org

library('genesysr')
genesysr::setup(server = "https://api.genesys-pgr.org",
  client_id = "[email protected]",
  client_secret = "your-private-secret")

# Obtain access tokens
genesysr::client_login()

Query Genesys

filters <- mcpd_filter(ORIGCTY = c("DEU", "SVN"))
accessions <- genesysr::get_accessions(filters)

# Sort columns, hand-pick first few columns
require(data.table)
setcolorder(accessions, unique(c("id", "instituteCode", "accessionNumber", "taxonomy.genus", sort(names(accessions)))))
