DeepMM targets chimeric contigs in metagenome-assembled genomes

A bioRxiv preprint describes DeepMM, a method that detects suspected misassembly junctions and splits contigs before microbial genomes are grouped into bins. In benchmark datasets, this reduced gene annotations that disagreed with sample-matched reference genomes.

LongPhase-TO reconstructs tumour haplotypes from tumour-only DNA

A bioRxiv preprint presents LongPhase-TO, a long-read method for reconstructing somatic haplotypes from tumour samples without matched normal DNA. In tests on eight datasets from six cancer cell lines, the method lengthened haplotype blocks and improved somatic variant-calling scores.

AmbientMapper Targets Contamination in High-Throughput Single-Cell Data

A University of Michigan team has introduced AmbientMapper, a computational method that estimates ambient chromatin contamination in combinatorial single-cell experiments. In a bioRxiv preprint, the authors report a 0.19% wrong-genome rate on a 26-genome reference panel and recovery of low-depth nuclei that standard pipelines discarded.
