Tahoe is a research-oriented platform for the development of numerical methods and models for the simulation of complex material behavior.

Detecting allelic biases from high-throughput sequencing data requires an approach that maximises sensitivity while minimizing false positives. Here we present Allelome.PRO, an automated userfriendly bioinformatics pipeline, which uses high-throughput sequencing data from reciprocal crosses of two genetically distinct mouse strains to detect allele-specific expression and chromatin modifications. Allelome.PRO extends approaches used in previous studies that exclusively analysed imprinted expression to give a complete picture of the “allelome” by automatically categorising the allelic expression of all genes in a given cell type into imprinted, strain-biased biallelic or noninformative. Allelome.PRO offers increased sensitivity to analyse lowly expressed transcripts, together with a robust false discovery rate empirically calculated from variation in the sequencing data.

Charmol is a cross-platform GUI/command-line based program for making high-quality pictures of molecular structures, nowadays working on Linux, MacOS and Windows. As output, it produces POV-Ray rendered images or files in VRML format. Charmol is capable of making pictures containing: - from small- to large-size molecules - more molecules together (different settings possible) - orbitals using molden and fchk files (GTO functions up to 'h' angular momentum supported) - surfaces using gaussian cube files (also color-mapped surfaces according to potential) - schematic representation of vibrations using arrows - user-defined arrows representing vectorial properties - measuring gauges - combinations of these features (more orbitals together, orbitals and arrows together etc.) Charmol allows for fine tuning of the final molecular design.

This is a collection of scripts and instructions on how to analyzing amplicon sequence data (i.e., 16S, ITS2, & other marker genes). I created this workflow to create a consistent set of methods for analyzing amplicon sequence data, from when you first receive the sequence data to statistical analyses & data visualization. All you need is to have the latest version of R installed, some experience with the command line & shell, and enough memory to run all of the programs. There are also instructions provided in case you are running these analyses via a computing cluster/Slurm workload manager. You can choose to go through the workflow using either an Rmd script, an html file, or a PDF, or via the homepage link provided. If you have questions or concerns, please don't hesitate to reach out. Thanks!

DNA and RNA nucleotide sequences are an ubiquitous element of all biological cells and are serving on one hand as a comprehensive library of capabilities for the cells and on the other as an impressive regulatory system to control cellular function. The presented multi-alignment framework (MAF) should give researchers a simple sequence alignment platform as a functional template, flexible enough to adjust all steps but also comprehensive enough to join many different tools and custom parameter combinations if in-depth analysis is necessary or advised in e.g. low read rate situations. The platform enables researcher to apply multiple sequence aligners and further pre- and postprocessing tools in flexible combinations to analyze the subtle to remarkable differences between different sequence alignment and processing algorithms applied to the same data basis.

Unix-based preparation and analysis toolbox for Nanomaterials and Room Temperature Ionic Liquids in Bulk and Slab using bash scripts, Gromacs tools and Matlab functions. NaRIBaS provides a framework that decouples user input parameter and terminal based command lines. NaRIBaS does not replace a simulation software and specific analysis tools like Gromacs, but it allows iterative repetition of tasks while changing specific input parameter. The toolbox is to be understood as a scripting framework rather than a black-box software. Task specific input and preparation or analysis function, are easy expandable to meet the scientific characteristic of constant changing properties. Concepts for efficiently storing and analysing large files in conjunction with graphical visualization and numerical data processing are presented in a Manual. A documented script collection that allows reproducing all simulations and analysis results presented in the Doctoral thesis of the author.

PepArML: An unsupervised, model-free, combining peptide identification arbiter for tandem mass spectra via machine learning.

Polymer simulation utilites for bead coarse-grained models of polymers. Includes 1) lattice monte carlo. Many kinds of lattices are supported. It shouldn't be a problem to implement any new specific one (discrete models) 2) off-lattice monte carlo and molecular dynamics (continuous models) Latter one is rebuild of earlier version of simpatico (http://gemini.cems.umn.edu/research/morse/code/simpatico/home.php) project. Input and output are based on PDB file format which is better to visualize with pymol. For specific non-pdb input/output of 2nd program there are convertation utils also available. Programs are expected to compile in gcc under cygwin or pure linux environment. Scripts to run many copies of program under pbs/torque cluster system are also available.

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/
