GESTALT is a method that uses genome editing to progressively introduce and accumulate diverse mutations in a DNA barcode over multiple rounds of cell division, thereby recording cell lineage relationships in the patterns of mutations shared between cells.
Further information about GESTALT, including links to data, reagents, source code, and phylogenetic trees for cell lineages of embryo and adult zebrafish, are available at http://gestalt.gs.washington.edu.

CADD is method that objectively weights and integrates diverse genomic annotations to a single, phred-scaled metric.
Further information about CADD, pre-computed CADD-based scores (C-scores) for all 8.6 billion possible single nucleotide variants (SNVs) of the human reference genome, and a tool for scoring of short insertions/deletions are available at http://cadd.gs.washington.edu.

Molecular inversion probes (MIPs) enable cost-effective multiplex targeted gene resequencing in large cohorts. However, the design of individual MIPs is a critical parameter governing the performance of this technology with respect to capture uniformity and specificity. MIPgen is a user-friendly package that simplifies the process of designing custom MIP assays to arbitrary targets. New logistic and SVM-derived models enable in silico predictions of assay success, and assay redesign exhibits improved coverage uniformity relative to previous methods, which in turn improves the utility of MIPs for cost-effective targeted sequencing for candidate gene validation and for diagnostic sequencing in a clinical setting.
MIPgen is available for non-commercial use at: http://shendurelab.github.io/MIPGEN.

LACHESIS is method that exploits contact probability map data (e.g. from Hi-C) for chromosome-scale de novo genome assembly.

Contiguity preserving transposition and sequencing (CPT-seq) is an entirely in vitro means of generating libraries comprised of 9216 indexed pools, each of which contains thousands of sparsely sequenced long fragments ranging from 5 kilobases to >1 megabase. This software, fragScaff, leverages coincidences between the content of different pools as a source of contiguity information for scaffolding de novo genome assemblies. FragScaff is complementary to Lachesis, providing midrange contiguity to support robust, accurate chromosome-scale de novo genome assemblies without the need for laborious in vivo cloning steps.
Further information about fragScaff, including source code, is available at: https://sourceforge.net/projects/fragscaff/files.

Microbial communities consist of mixed populations of organisms, including unknown species in unknown abundances. These communities are often studied through metagenomic shotgun sequencing, but standard library construction methods remove long-range contiguity information; thus, shotgun sequencing and de novo assembly of a metagenome typically yield a collection of contigs that cannot readily be grouped by species. MetaPhase is software that exploits chromatin-level contact probability maps, e.g., as generated by the Hi-C method, to reconstruct the individual genomes of microbial species present within a mixed sample.
