In terms of speed, all FEP calculation in Flare V4 are significantly faster thanks to an improved algorithm with a 20% increase in performance, and they are fully parallelizable. The implementation of the Open Forcefield now allows users to update themselves.įEP has been implemented in Flare DOI and this release improves performance. The key new features of Flare V4 includes significant improvements to Free Energy Perturbation (FEP), new and improved force fields, new Dynamics analysis tools, plus new and improved GUI functionality. This project is licensed under the MIT LicenseĪbout a year ago I wrote a review of Flare a tool for structure-based drug design.
The GitHub page contains detailed instructions for installation. if topology provided, interaction energy grids can be calculated for transient pockets and channels (experimental).can now read Gromacs XTC, netcdf and dcd trajectories.Yields now slightly better results than the original implementation. druggability score has been reoptimized vs original paper.pocket flexibility using temperature factors is better considered (less very flexible pockets on very solvent exposed areas).is now able to consider explicit pockets when you want to calculate properties for a known binding site.What's new compared to fpocket 2.0 (old sourceforge repo) The platform is suited for the scientific community willing to develop new scoring functions and extract pocket descriptors on a large scale level.
The fpocket suite of programs is a very fast open source protein pocket detection algorithm based on Voronoi tessellation. If you are using the Homebrew package manager, you can install Modeller on recent Macs (either Intel or Apple Silicon, M1) by simply running brew tap salilab/salilab MODELLER implements comparative protein structure modeling by satisfaction of spatial restraints, and can perform many additional tasks, including de novo modeling of loops in protein structures, optimization of various models of protein structure with respect to a flexibly defined objective function, multiple alignment of protein sequences and/or structures, clustering, searching of sequence databases, comparison of protein structures, etc. The user provides an alignment of a sequence to be modeled with known related structures and MODELLER automatically calculates a model containing all non-hydrogen atoms. MODELLER is used for homology or comparative modeling of protein three-dimensional structures. They see about a 20% performance improvement with gfortran-10 on a 2020 Mac Mini (M1) compared to Intel Fortran on a 2018 Mac Mini (Intel). They used the gfortran that's part of the gcc homebrew package (). Modeller written in Fortran90 has been ported to Apple Silicon
