Peptide Vaccine Analysis Tool (PVAT) is an optimization software that predicts the best possible peptide stretches in a given protein sequence based on two factors: 1. the surface exposure of the peptide stretches, and 2. their susceptibility to mutation.

Phaistos is a framework for all-atom Monte Carlo simulations of proteins. It incorporates several advanced probabilistic models of protein structure for conformational sampling, efficient move-algorithms and the OPLS and PROFASI forcefields.

Phobos is to be used for recording rodents' behavior during the thigmotaxis (open-field) and the elevated plus-maze tests. Phobos provides the possibility to easily calculate all possible experimental parameters at once immediately after the evaluation of the fear/anxiety level of each animal. All extracted files can be readily combined to one in order for statistical analyses to be performed. If you use Phobos for your research, please cite: Telonis AG, Margarity M.Phobos: a novel software for recording rodents' behavior during the thigmotaxis and the elevated plus-maze test.

Phylogenetic Representativeness is a method for estimating adequacy of taxon sampling for phylogenetic studies. Through a series of statistics generated by PhyRe, it is possible to evaluate taxon coverage within a given group.

A python/C++ framework for Bayesian phylogenetic analysis.

PhyloTrack is a JavaScript--based software tool that integrates the D3.js library for data visualization with the JBrowse tool for genome browser representation. It requires a phylogenetic tree of the common Newick data format as input, as well as three meta data files for samples, clade-defining nodes and clade color definitions - all in tab delimited format. Functionality within PhyloTrack shows the informative markers at each node in the phylogenetic tree, therefore highlighting clade-defining polymorphism. This functionality has been implemented using the tabix tool on the server side, providing simple and rapid access to the information at each tree node, including informative SNPs stored in VCF-similar files. These informative variants have been established by comparing allele frequencies between strain-types using ancestral node comparisons and FST measures of population differentiation.

Given the peptides (T-cell epitopes) PolyCTLDesigner selects flanking sequences to optimize TAP-binding and joins resulting oligopeptides into a polyepitope in a way providing efficient liberation of potential epitopes by proteasomal and/or immunoproteasomal processing and minimizing the number of junctional epitopes. For constructing polyepitopes PolyCTLDesigner utilizes known amino acid patterns of proteasome cleavage and TAP-binding specificity. PolyCTLDesigner is also able to choose antigenic peptides covering selected HLA repertoire with desired redundancy rate. Given the antigen sequences PolyCTLDesigner is also able to select T-helper epitopes. For predicting T-cell epitopes it uses TEpredict.

For user guide of the tool, please visit https://github.com/ozgurcanarican/PredDRBP-MLP

A simple tool to design DNA primers for mutagenesis in BGME lab (JHU). Allows users to select or enter background sequence and add current and new mutations. During the design process, users are presented with various updating checks to guide them.

ProtPOS is a self-contained, lightweight, and easy-to-use software package for predicting the preferred orientation of protein on a given surface upon initial adsorption. It searches quickly for the low energy protein poses in all translational and rotational degrees of freedom of the protein with respect to the surface using particle swarm optimization. Each successful run returns the lowest energy orientation of the protein on the surface in PDB format, which is readily used for MD simulations. ProtPOS is implemented in Python, making use of the PyMOL library for generating protein conformations and calling GROMACS externally to calculate protein-surface interaction energies. https://cbbio.online/software/protpos/

The Protein Geometry Database hosts the development code for a flexible database for searching protein geometry, as well as a library for accessing this data for protein modeling & refinement programs.

The C Protein Folding Library is a minimalistic, high-performance modular library of C functions and data structures for computing folding simulations of proteins on a wide variety of computer hardware.

PepT-IDE is a protein analysis tool that is used for multiple sequence alignment, 3D visualization and displaying protein contact maps for protein sequences and structures. It also has feedback communication between the different views of the protein.

This project implements an algorithm for segmenting protein sequences into smaller meaningful blocks. The method is based on the pure statistical approach and it uses an analogy between proteins and natural language.

Protenix is an open-source, trainable PyTorch reimplementation of AlphaFold 3, developed by ByteDance with the goal of democratizing high-accuracy protein structure prediction for computational biology and drug-discovery research. Protenix provides a complete pipeline for turning protein sequences (with optional MSA / sequence alignment) or structural inputs (e.g. PDB/CIF) into full 3D atomic-level structure predictions. It supports both “full” models and lightweight variants such as “Protenix-Mini,” offering a trade-off between speed/compute cost and predictive accuracy — making structure prediction accessible even in resource-constrained environments. The project also includes support for constraints (e.g., specifying residue- or atom-level contact constraints, or pocket constraints) to guide predictions toward biologically or experimentally relevant conformations, which enhances its utility for tasks like modeling complexes, ligands, or antibody–antigen interactions.

Sign up to our mailing list at http://www.protospacer.com/contact.html. Protospacer allows researchers to build, analyze, and share their own database of CRISPR target-sites. This enables the development of custom libraries and helps to transfer the CRISPR technology to new organisms. Each Protospacer database is a simple catalogue of all possible Cas9 target-sites within a given FASTA sequence, i.e. all NGG/NAG sites. Protospacer then allows the user to sub-select targets from the database by gene ID, by exon/intron/UTR location, by sequence similarity, or by genomic co-ordinate. From here, users are able to evaluate potential off targeting, to export results in FASTA format or tabulated (e.g. for Microsoft Excel), and to connect to the Integrative Genomics Viewer (IGVref) and view target-sites in the context of genomic annotations, amino acid translations, and HT-Seq data (for off-target validation). We provide online video tutorials and a toy database from our main website.
