The MDFF graphical user interface (GUI) in the Modeling section of the VMD Extensions menu has been updated to reflect the use of multiple maps in addition to many other usability improvements. The MDFF setup plugin now supports the use of multiple density maps in a single MDFF simulation.

VMD 1.9.3 contains several updates for the Molecular Dynamics Flexible Fitting (MDFF) Method.

Documentation and screencast tutorials are available on the plugin website.

In addition to the major tools described above, ffTK contains several new but smaller features, such as the ability to output the MM relaxed conformational scan used as the baseline in dihedral fitting, and bug fixes.

Numerical analysis can also be performed to provide detailed information on how all dihedrals change throughout the scan, helping to identify highly coupled torsions that often complicate parameter fitting. The key function of this tool is to load each optimized structural conformation into VMD and to construct a color plot of the associated potential energy surface (PES) for side-by-side comparison.

A new analysis and plotting utility, named Torsion Explorer (accessable from the Scan Torsions tab), is designed specifically to aid in troubleshooting difficult dihedral parameter fits providing visual and numerical analysis of the relaxed QM torsion scans.

ffTK can now leverage the output from this resource to automatically prepare the PSF+PDB files required by ffTK, analyze penalty scores associated with each returned parameter, visualize all instances of a given parameter directly within the molecular structure, and write a parameter file that is initialized to the CGenFF values as a starting point for refinement. The CGenFF Program web server performs an analysis of molecular structure and assigns parameters based on analogy to molecules contained with in the standard CGenFF parameter set.

A new tool has been added to the BuildPar toolset that processes output from the CGenFF Program webserver to automatically construct all of the structural and parameter input required for entry into the ffTK parameterization workflow, bypassing a common stumbling block in structure preparation.Two new major features have been added to the Force Field Toolkit for the VMD 1.9.3 release. The Force Field Toolkit (ffTK) plugin provides a comprehensive toolset for the development of CHARMM-compatible (e.g., CGenFF) force field parameters, including charges, bonds, angles, and dihedrals.QwikMD incorporates logging of procedures for reproducibility, and to enable simulation workflows and protocols to be shared among users. For more information, the user is redirected to web-pages through links present in the bottom of the information window. Each "info button" generates a window where the user can find fundamental information related to Molecular Dynamics simulations, such as the description of solvent models and protein structure, as well as short explanations of the options available in QwikMD graphical interface and the actions triggered by the buttons. While making it easy for a new user to perform simulations, QwikMD also works as a learning tool with "info buttons" that guide the user and provide the theoretical background underlying the procedures that are followed. Connecting the user-friendly molecular graphics program VMD to the widely adopted MD program NAMD, the new QwikMD plugin guides users to prepare common molecular simulations in just a few minutes, allowing for quickly study of point mutations, partial deletions or even steering experiments.

Now open up the terminal and go to the directory, where the images from the movie maker are saved. You can either write the path to a folder in either “Selection” or manually select the path to that folder using your mouse.

Also, to change the location of a folder that will have and save all the JPEG pictures, press on “Set working directory:” button which is shown below.

Lastly, make sure to put a title on your movie in a box on next to “Name of movie”. This will take take many spanshots of your movie amd save with a “.jpeg” extension. The last button that you should press is “Format” and select “JPEG frames(ImageMagick)”. Next press on the “Movie Setting” and select “Trajectory”, these steps are shown below: In that window, press on the “Renderer” button and select “Internal Tachyon(Ray Tracer)” from the dropdown menu. Those steps should take you to a window called “VMD Movie Generator” shown below. This following image shows the steps you chose: After loading your files to VMD, press on a Window called VMD Main and press on Extension menu and select “Visualization”, and “Movie Maker” from the dropdown menu.
