Open Babel is a chemical toolbox designed to speak the many languages of chemical data.

RepEnrich is a method to estimate repetitive element enrichment using high-throughput sequencing data.

NOVOPlasty - The organelle assembler and heteroplasmy caller. NOVOPlasty is a de novo assembler and heteroplasmy/variance caller for short circular genomes..

adapter trimmer for Oxford Nanopore reads

Screen a bacterial assembly (contigs/CDS or proteins) for nucleotide or protein sequences. Pipeline that screens for presence of genes of interest (GOI) in bacterial assemblies. Generates multiple CSVs and plots that describe which genes are present and how variable their sequence is. Can use DNA or protein query sequences (GOIs) and DNA contigs/fastas or protein fastas as database (db) to search in.

maeparser is a parser for Schrodinger Maestro files.

Tandem repeat genotyping with long reads, being a modified version of HipSTR.

Processes 96-well plate absorbance data through blank subtraction, regression fitting, and dilution correction to report sample concentrations with QC flags for BCA, Bradford, and ELISA workflows. A browser calculator supports interactive grid entry with CSV and PDF export; a Python library and command-line tool submit the same parameters to the Pepkio Tools API for scripted and pipeline use. Calculator arithmetic is hosted remotely; the client transmits plate layout and absorbance values and returns model comparison, per-sample concentrations, and shareable run identifiers.

Estimates PCR primer melting temperatures and polymerase-specific annealing temperatures from sequence and buffer inputs, with per-pair QC for hairpins, dimers, and Tm balance. A browser calculator supports interactive single-pair and batch entry (up to 200 pairs) with method comparison and export; a Python library and command-line tool submit the same parameters to the Pepkio Tools API for scripted and pipeline use. Calculator arithmetic for the API client is hosted remotely; sequences are transmitted for programmatic runs while the web interface performs calculations in the browser.

Mol Biology Tools is a free browser-based collection of molecular biology utilities for routine sequence analysis, primer design, Sanger sequencing primer planning, cloning setup, and wet-lab calculations. The site includes tools for PCR primer design, Sanger primer design and primer walking, primer binding checks, restriction site analysis, reverse complement generation, ORF and protein translation, codon optimization, ligation calculations, molarity calculations, dilution calculations, and multi-solute solution recipe preparation. The tools run in the browser and are intended for quick experimental planning without requiring logins or server-side sequence upload.

Plans PCR and qPCR master-mix reagent volumes from stock and final concentrations, reaction counts, and pipetting overage, with consolidated totals when several assays are prepared together. A browser calculator supports interactive recipe entry with printable bench sheets; a Python library and command-line tool submit the same parameters to the Pepkio Tools API for scripted and pipeline use. Calculator arithmetic is hosted remotely; the client transmits parameters and returns structured volume tables, dilution warnings, and shareable run identifiers.

Computes laboratory solution preparation parameters—powder mass to weigh, stock and diluent volumes for single dilutions, and multi-step serial concentration tables—with correction for hydrated salts and supplier purity. A browser calculator supports interactive prep planning with saved recipes and shareable links; a Python client and command-line tool submit the same parameters to the Pepkio Tools API for scripted and pipeline use. Calculator arithmetic is hosted remotely; the client transmits parameters and returns structured protocol steps and shareable run identifiers.

Comprehensive set of programs for phylogenetic analyses; available for PC and Mac; source code available for easy compiling in UNIX.

Web application and service for visualizing small- to medium-scale models of gene regulatory networks. It automatically lays out either an unweighted or weighted network graph based on an Excel input spreadsheet containing an adjacency matrix where regulators are named in the columns and target genes in the rows. It is best-suited for visualizing networks of fewer than 35 nodes and 70 edges and has general applicability.

FlavoTyper is a bioinformatics tool that performs in silico serotyping of Flavobacterium psychrophilum genome assemblies.

MONAI Label is an intelligent open source image labeling and learning tool that enables users to create annotated datasets and build AI annotation models for clinical evaluation. MONAI Label enables application developers to build labeling apps in a serverless way, where custom labeling apps are exposed as a service through the MONAI Label Server.

The ProteinsPlus web server aims to support life scientists in working with protein structures. Protein structures are the key to understanding protein function. They are an important resource in many biotechnological application areas from pharmaceutical research to biocatalysis. ProteinsPlus focuses on protein-ligand interactions. The server provides support for the initial steps of dealing with protein structures, namely structure search, quality assessment, and preprocessing. JAMDA enables users to perform an on-the-fly molecular docking of up to five molecules. The poses can then be visualized in 2D (PoseView, PoseEdit). Furthermore, advanced options, such as protein pocket detection (DoGSite), prediction of water molecule positions (WarPP), protein structure ensemble generation (SIENA), prediction of metal coordination (METALizer), the analysis of solvent channels in protein crystals (LifeSoaks), or the categorization of protein-protein-interfaces (HyPPI) are supported.

SeqBench is a free collection of browser-based tools for working with DNA, RNA and protein sequences, including reverse complement, translation, ORF finding, GC content, primer melting temperature, restriction site analysis, codon optimization, pairwise alignment and plasmid visualization. All computation runs client-side in the browser, so input sequences are never uploaded to a server.
