Latent strain analysis partitions reads into sets likely belonging to the same genome, using the covariance of k-mers across many samples.
Documentation for LSA, including a "getting started" tutorial with accompanying test data, and step-by-step instructions for analyzing large collections, can be found at: http://latentstrainanalysis.readthedocs.org/
The source code can be found on the github page
