With an easy-to-follow syntax and flexible composition rules, the tool greatly simplifies movie design, allowing the user to focus on conceptual rather than technical issues. These shortcomings prompted us to create Molywood, a Python tool capable of managing complex moviemaking workflows across a range of utilities, including the open-source utilities FFmpeg and Imagemagick, Python’s Matplotlib and VMD with its extended Tcl scripting capabilities ( Humphrey et al., 1996). While molecular movies of excellent quality do exist in the literature, they are usually a result of a lengthy work on integrating workflows, automatizing and post-processing.
Simultaneously, platforms such as Molecular Maya are commercial and thus not accessible to many researchers. In fact, a very limited choice of such tools exists today: VMD’s Movie Maker remains limited to simplest cases, BioBlender and ePMV require programming and/or Blender skills ( Andrei et al., 2012 Johnson et al., 2011), while PyMOL’s eMovie effectively vanished from the Web ( Hodis et al., 2007 Hsin et al., 2008). On the other hand, researchers often find existing tools inadequately suited to these challenges. Not only are publishers starting to actively encourage the use of multimedia in the new enhanced, web-only article formats, but also science communication has become increasingly visual due to the proliferation of science-oriented blogs, vlogs and social media channels ( Welbourne and Grant, 2016). This situation could be rectified through widespread adoption of molecular movies as a complementary visual aid in the dissemination of scientific findings ( McGill, 2008). However, the scientific communication of these findings primarily relies on still images and figures, often obscuring or distorting the structural insights.
The two revolutions in high-resolution structural biology-first in X-ray crystallography, second in cryogenic electron microscopy (cryo-EM) imaging ( Stuart et al., 2016)-resulted in tens of thousands of unique protein structures being deposited in public databases, ultimately providing us with an atomistic-level insight into the peculiar world of molecular shapes and conformational changes. 14: 33-38.Since the groundbreaking resolution of the 3-dimensional structure of myoglobin in 1960 ( Kendrew et al., 1960), our understanding of processes of life has increasingly relied on the visualization of molecules.

Installation Use the following command to install this title with the CLI client: $ sbgrid-cli install vmd Copy to clipboard Available operating systems: Linux 64, OS X INTEL.I guess this gives a per-frame image smoothing effect as thepotentially hard edged rendered image is reduced to an anti-aliased frame.

* loaded every 20th frame (about 1000 from 20k) * smoothing window of 4 * internal Tachyon ray tracer * image smoothing on * half size reduction * 30 FPS (NTSC) * MPEG outputĪpparently a good trick to get nice looking animations is to double therendering window then set the movie generator to half-size the result.

I haven't done a formal test of this, but my laptop, with 48 CUDA 3 processing cores, seems to do much better, smoother, and faster rendering than my Mac Pro (which does not have a compatible CUDA card). Set DisplayRendermodeGLSL to do OpenGL/CUDA rendering. I have found that a 4ns smoothing window reduces the jitter without eliminating interesting side chain motion. For each representation, set the Trajectory to smooth over several frames. Clicking on a representation will show or hide it.ĥ. You can then play with the different kinds of views (coloring, style, transparency) for each representation individually.Ĥ. water and within 3 of protein would show all water molecules within 3A of an atom associated with a protein. protein and resid START1 to STOP1 START2 to STOP2 ¦ is a common entry. The selection box can be used to specify what you want to show. Use Create Rep to create multiple representations of the structure. This will align the entire structure through all frames and have resids START to STOP as stationary as possible.ģ. Go to ExtensionsAnalysisRMSD Tool and enter protein and resid START to STOP, then click on Align. Figure out what region you want to fix in the structure. The background option will render frames as they’re loaded.Ģ. Make sure you choose load all frames at once, rather than background. to 20, if the generated frames are at a rate of 50 ps per frame). The stride feature in the VMD trajectory loader dialog lets you set this (e.g. A 1 us simulation would only need 1000 frames. Just load 1 frame for every 1ns of simulation time.
