Please does anyone know how to use this function? I have a graph and I would like to get the list/number of all unique gene products. I'm guessing that is what this function is supposed to do, but the prototype at the function description is empty for the usage. Is there a bug? Or does anyone know how to use it? I guess I could just go through all the terms in my graph and for each term keep a hash of all the unique gene products but that'll be slightly more cumbersome. I appreciate the help. Thanks!
