New tools speed variant annotation, GWAS, and epigenomic and cytometry analysis

The items share a tooling emphasis: converting established omics analyses into faster or more accessible, reproducible software. Two preprints focus on computational throughput. TorchGWAS applies GPU-batched, covariate-adjusted association testing across thousands of quantitative phenotypes, and vcfilt reports a 12.2x single-thread speedup over bcftools 1.18 on 1000 Genomes chr20 data. fastVEP reimplements the Ensembl VEP annotation engine in Rust, annotating GIAB HG002 WGS in 86 s and running 22-24x faster than VEP. A second group prioritizes accessibility and workflow packaging. trackDJ provides scripted, publication-quality epigenomic visualization in R, FlowWeb pairs R/Bioconductor with a GUI for flow cytometry QC, gating, and cell cycle analysis, and REPLAY automates Repli-seq processing from FASTQ to replication timing profiles. GNOMES addresses normalization and differential binding for CUT&RUN and ChIP-seq. The thread is partial: performance and usability goals differ, and the items do not share a common deployment model. What is distinctive here is the pairing of speed-oriented reimplementation with explicitly reproducible, end-to-end packaging.
