Opening file error at end(?) of run

[terrycojones]

I tried a run using sequence data from Richard O. It ran without error (though with many rounds of doing 125 GOM constructions) for maybe 10 hours, then crashed as follows:

		Round 10
			Bootstrap the data
			Construct a dendrogram from the bootstrapped data
			Compute similarity cut off for each taxonomic class based on the bootstrapped data
			Propose a taxonomic class to each unclassified virus and evaluate the taxonomic assignments based on the bootstrapped data
		Propose a taxonomic class to each unclassified viruses, using the 1-nearest neighbour algorithm
		Evaluate the taxonomic assignments
		Creat a bootstrapped dendrogram
	Construct GRAViTy heat map with dendrogram
