Hydrogen-deuterium exchange coupled to mass spectrometry permits analysis of structural dynamics, stability, and molecular interactions of proteins. Resolving isotopic fine structure during mass spectrometry has been recently demonstrated to allow direct detection and quantification of deuterium incorporation distinct from peaks corresponding to non-deuterium incorporated natural abundance heavy isotopomers. Here, we present a graphical tool that allows for a rapid and automated estimation of deuterium incorporation from a spectrum with isotopic fine structure resolved. Given a peptide sequence or elemental formula, the distribution of deuterium-associated mass-to-charge ratios is calculated based on a particular charge state corresponding to the molecular species resolved in an input mass spectrum. Peaks in the input mass spectrum fitting within bins corresponding to these values are used to determine the distribution of deuterium incorporated.

This is a Matlab software package for single molecule FRET data analysis.

DRCS (Dimensionless Reaction Coordinate Software) calculates a dimensionless reaction coordinate for chemical reactions that can be used to classify transition states (and other geometries along a reaction path) as either early or late.

Elastic network models (ENMs) have been shown to generate the dominant functional equilibrium motions of biomolecules quickly and efficiently. MAVEN simplifies ENM generation, allows for diverse models to be used, and facilitates useful analyses.

MORphological PHenotype Extraction (MORPHE) is a suite of automated image processing, visualization, and classification algorithms to facilitate the analysis of heritable and clonal red-to-green transitions that occurred during the growth of a colony.

primeHandle is a set of data management tools in support of the PrIMe Initiative (http://primekinetics.org). primeHandle includes graphical user interfaces for searching through data collections, editing and submitting data to the PrIMe Data Depository.

Acquisition software for electron microscopes. Runs on FEI Tecnai and Titan microscopes and is usable in material and life science applications

This project contains tools for using the TX-TL cell-free expression system. These tools include component models for simulating and analyzing biomolecular circuits, as well tools for composing circuits and creating more complex systems. NOTE: This project has been shifted to GitHub: https://github.com/BuildACell/txtlsim

TrajLab (which stands for TRAJectory LABoratory) consists of two sets of MATLAB program packages. While subproject MolDynSim deals with generation of molecular trajectories (and other aspects of molecular simulation), subproject MetaStable is dedicated to the analysis of molecular trajectories by detecting metastable conformations (as well as other analysis techniques). Note that each of the two sub-projects has its own SVN repository, wiki, tracker, etc: Probably TrajLab is the first attempt for a general purpose molecular simulation package in MATLAB. While the authors are aware that many other highly specialized and highly optimized program packages for the same purpose exist (e. g. AMBER, GROMACS, NAMD, etc.), the MATLAB environment offers easy access to manipulating the codes, testing novel algorithms, non-standard force fields and performing all kinds of numerical experiments. To be used mainly in teaching!

WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations, partly also classical or quantum-classical Liouville equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry, including quantum optimal control. Allowing for visualization of dynamics 'on the fly', WavePacket is easy to use . First established in 2004, the present Matlab version is in a stable, mature state. Further development mainly by Burkhard Schmidt at WIAS and FU Berlin.

This package of MATLAB routines with accompanying GUI allows scientific users to measure the 3D location of single molecules when using the double-helix point spread function (DH-PSF) widefield microscope. Version 2 also includes code that facilitates combining localization data from two spectral channels using a locally-weighted quadratic 3D registration function Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads) - DH localization is performed through template matching and subsequent double Gaussian fitting - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions - Two spectral channels are registered by generating a locally-weighted quadratic mapping function from control point pairs

This package includes a collection of MATLAB files which are designed to: 1. Given a calibration scan of the image of a point emitter with an engineered point spread function (PSF), 2. Perform a phase retrieval algorithm based on maximum likelihood estimation (MLE) of a phase aberration term which is added to the theoretical pupil function of the imaging system. 3. Use the phase-retrieved pupil function to perform single-emitter localization. Accompanying publication available here: https://doi.org/10.1364/OE.25.007945

Esra is a 100% pure java library for the interactive analysis of molecular mechanics data. Mangles your data in your favorite scripting language.

gfit creates an interface between computational models and experimental data and provides tools for their analysis

This is a simple Octave script which calculates the frequencies/normal modes from an nwchem generated hessian matrix. The advantage of having a separate script for this is that you can use the same hessian to calculate frequencies for different isotopic substitutions i.e. you only have to run one nwchem calculation. The script is finished in its current form in the sense that it is feature complete. Feel free to amend, translate, copy, steal etc. See the README in the code repository for instructions. Installation: Simply download the file and start Octave in the download directory.

SpecMark (spectral Markov) is a method for calculating the joint probability distribution over species in a regulatory network.
