However, software for learning quantitative models from these data is lacking. Here we describe Sort-Seq Tools, a software package that allows multiple types of quantitative models to be fit to massively parallel data in multiple different ways. We demonstrate Sort-Seq Tools on both simulated and published data from Sort-Seq studies, massively parallel reporter assays, and deep mutational scanning experiments. We observe that, as an inference method, information maximization generally outperforms both least squares optimization and enrichment ratio calculations. %U https://www.biorxiv.org/content/biorxiv/early/2016/05/21/054676.full.pdf
