BiPad – Web Server for Modeling Bipartite Sequence Elements

BiPad

:: DESCRIPTION

The Bipad Server is a web interface to predict sequence elements embedded within unaligned sequences. Either a bipartite model, consisting of a pair of one-block position weight matrices (PWM’s) with a gap distribution, or a single PWM matrix for contiguous single block motifs may be produced. The Bipad program performs multiple local alignment by entropy minimization and cyclic refinement using a stochastic greedy search strategy. The best models are refined by maximizing incremental information contents among a set of potential models with varying half site and gap lengths.

PottersWheel 4.0 – MatLab Toolbox of Mathematical Modeling of Dynamical Systems

PottersWheel 4.0

:: DESCRIPTION

PottersWheel is a MATLAB toolbox for mechanistic mathematical modeling. It allows reaction network or ordinary differential equation (ODE) based modeling.

PottersWheel has been developed to provide an intuitive and yet powerful framework for data-based modeling of dynamical systems like biochemical reaction networks. Its key functionality is multi-experiment fitting, where several experimental data sets from different laboratory conditions are fitted simultaneously in order to improve the estimation of unknown model parameters, to check the validity of a given model, and to discriminate competing model hypotheses. New experiments can be designed interactively. Models are either created text based or using a visual model designer. Dynamically generated and compiled C files provide fast simulation and fitting procedures. Each function can either be accessed using a graphical user interface or via command line, allowing for batch processing within custom Matlab scripts.

ABM-TKI 0.11 – Multi-scale Agent-Based Brain Tumor Modeling

ABM-TKI 0.11

:: DESCRIPTION

ABM-TKI is a tool, employing agent-based model (ABM), to simulate brain tumor growth that includes an EGFR signaling pathway together with a related cell-cycle pathway, angiogenesis and tyrosine kinase inhibitors (TKIs) treatment. The users can apply this tool to predict the responses of brain cancer to TKIs, and to reveal the dual role of angiogenesis during TKI treatment.

LigandScout 3.12 – Pharmacophore 3D Modeling

LigandScout 3.12

:: DESCRIPTION

LigandScout is a fully integrated platform for accurate virtual screening based on 3D chemical feature pharmacophore models. It offers seamless workflows, starting both from ligand- and structure based pharmacophore modeling, and includes novel high performance alignment algorithms for excellent prediction quality with unprecedented screening speed. Additionally, we have included user-friendly screening analysis tools, including the automated generation of ROC curves for performance assessments. All functions are accessible through a well elaborated graphic user interface that reflects our years of experience in creation of the most user-friendly pharmacophore modeling tools. The algorithms are scientifically validated and based on our well-established knowledge in pharmacophore research, while the application corresponds to state-of-the-art information technology.
