(Getting this conversation back on the list) Gabriele Sales predicts the fix for the problem reported by Hamid will be in devel before long. - Paul Begin forwarded message: > From: Gabriele Sales <gabriele.sales at="" unipd.it=""> > Subject: Re: Fwd: [BioC] edge-less pathways in graphite > Date: April 26, 2012 1:41:56 AM PDT > To: Paul Shannon <pshannon at="" fhcrc.org=""> > > Dear Paul, > > we have checked this pathway and, in fact, we have found a problem. > > Our conversion software emits the following error: > > [ERROR] in pathway "path:hsa04012": a relation references element 54 > that is either undefined or belongs to an invalid type > > This kind of error is severe enough that any further activity on the > pathway topology is aborted.
