Machine learning is a powerful tool for classifying images in a time series, such as the developmental stages of embryos. We built a classifier using only bright-field microscopy images to infer nematode embryonic stages at high throughput.

The ProteinCartography pipeline identifies proteins related to a query protein using sequence- and structure-based searches, compares all protein structures, and creates a navigable map that can be used to look at protein relationships and make hypotheses about function.

We want to find and use evolutionary innovations to solve present-day problems. We developed NovelTree, an efficient phylogenomic workflow that will empower us to decode the evolutionary traces of these innovations across the tree of life.

Horizontal gene transfer (HGT) is the exchange of DNA between species. It can lead to the acquisition of new gene functions, so finding HGT events can reveal genome novelty. preHGT is a pipeline that uses multiple existing methods to quickly screen for transferred genes.

The increasingly large number of sequences available in public databases makes searches slower and slower. We clustered the NCBI non-redundant protein database and calculated taxonomic info for each cluster. This collapses similar sequences and reduces the database by over half.

We want to seamlessly process and summarize metagenomics data from Illumina or Nanopore technologies. We built a Nextflow workflow that handles common metagenomics tasks and produces useful outputs and intuitive visualizations.

Constraining motile microorganisms for live imaging often requires costly microfluidics or optical traps to keep them in view. We used patterned stamps and agar to make versatile, inexpensive “microchambers” and offer a way to predict the right chamber size for a given organism.

We want to swiftly generate genome assemblies and produce quality control statistics to gauge the need for more curation. We built a Nextflow pipeline that assembles Illumina, Nanopore, or PacBio sequencing reads for a single organism and runs QC checks on the resulting assembly.

The sourmash Python package produces many outputs that describe the content and similarity of sequencing data. We developed a new R package, sourmashconsumr, that lets a wider range of users easily load, analyze, and visualize those outputs in R.

seqqc is a Nextflow pipeline for quality control of short- or long-read sequencing data. It quickly assesses the quality of sequencing data so that it can be posted to a public repository before analysis for biological insights. Faster open data, faster knowledge for everyone.

Cells can be highly motile, moving in and out of a microscope’s field of view. Understanding complex life cycles is difficult without continuous observation. To overcome this challenge, we’ve developed a 3D-printed microchamber device to confine cells for long-term visualization.

Researchers studying any organism with genomic data can follow this simple walkthrough to create sets of barcoded probes for the multiplexed FISH technique called MERFISH. We’re sharing interactive code notebooks that can be adapted to design barcoded FISH probes for any species.
