Hi,

Please find more information, with a simple example.
The problem happened when referencing openBEL annotation files. Please find below a simple bel file that generate the error

##################################################################################

SET Species = "9606"

And the command line bel2rdf.rb --bel sample.bel --format turtle > sample.ttl
