Welcome to the Latent Strain Analysis (LSA) code repository!
LSA was developed as a pre-assembly tool for partitioning metagenomic reads. It uses a hyperplane hashing function and streaming SVD in order to find covariance relations between k-mers. The code, and the process outline in LSFScripts in particular, have been optimized to scale to massive data sets in fixed memory with a highly distributed computing environment.
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/
These changes are needed to get SciPy functioning again.
