Re: Problem with BatchSwarm and EZGraph

[Paul E Johnson]

Does a gui version of the same program run and give the graph you want? 
I think this looks funny because you do createSequence, which as far as
I recall should not work if you pass through a whole collection. you
need a createAverageSequence or something that can summarize the
collection.
