Since April 2013, YASARA is available for selected Android smartphones and tablets,.. providing today's most feature-complete mobile molecular modeling environment, including interactive MD simulations.. Tablet prices start at 175 EUR,.. two videos and all the details are available here.. The 3D Molecular Modeling Lab for 250 EUR.. Stereoscopic 3D molecular modeling hardware.. has become easily affordable, so that entire classrooms can enjoy this unique experience.. The image on the right shows the easiest and cheapest solution: 3D vision is provided using 'passive stereo', where the images for left and right eye are shown in odd and even pixel lines and separated using flicker-free polarized glasses.. The first popular screens with this feature were the Zalman ZM-M215W, ZM-M220W and ZM-M240W, costing around 200 EUR.. Unfortunately it appears that Zalman discontinued this product line, so they are now mostly available as refurbished second hand models.. But there are many follow up products, googling for.. passive stereo odd even.. finds e.. the LG D2342P, the HP 2311x, the AOC e2352Phz or the Viewsonic V3D231.. The big advantage is that this type of display is directly supported by YASARA with.. any.. graphics card and.. operating system (no expensive Quadro/FireGL cards or special video drivers are needed).. You can move your molecules through 3D space using the.. Connexion 3D SpaceNavigator.. with six degrees of freedom.. Order now for 50 EUR.. Notes:.. The ZM-M220W has a resolution of 1680x1050 pixels.. The polarized glasses ensure that the left eye sees only the odd pixel lines, while the right eye sees the even lines.. So the resolution is reduced to 1680x525 pixels per eye as soon as the glasses are put on.. This is hardly noticeable when looking at molecules, but becomes apparent when looking at characters.. Text is therefore harder to read than with alternative, more expensive stereo solutions.. Without glasses, the screen behaves just like any other screen and can be used for everyday work.. It has a quite glossy surface, reflections can be a problem in bright rooms, but are hardly noticeable in somewhat darker 'molecular modeling caves'.. At least YASARA Model is required.. High Resolution 3D Modeling for 350 EUR.. High resolution 3D stereo with shutter glasses.. is the next higher level, since it does not suffer from the reduced resolution of the Zalman screens above.. The probably easiest solution with the best price/performance ratio is the.. Viewsonic V3D241wm.. shown on the right.. The screen with a 24"/60cm diagonal has a resolution of 1920x1080 pixels and a non-reflective surface, it is thus well suited for everyday work.. It functions with every operating system and every graphics card (nVIDIA/AMD) that can display quad-buffered stereo with 100 or 120Hz at a resolution of 1920x1080 pixels.. The shutter glasses are included in the 350 EUR package.. A slightly more expensive but also more commonly used and more flexible solution is.. nVIDIA's 3D Vision system.. , check the guidelines.. here.. Other suppliers of 3D glasses are.. eDimensional.. RealD.. Your graphics card must have a dual-link DVI connector and support quad buffered OpenGL stereo, a feature which is normally only available in.. workstation products like nVIDIA Quadro.. and AMD FireGL.. You do not need the very expensive high-end Quadros with mini-DIN stereo connector, since the shutter glasses are supplied with the screen and plug into the screen with a cable, neither emitter nor batteries are required.. Only one pair of glasses can be connected, so this system is for one person only.. And since the monitor does not know the difference between left and right image, you may have to swap left and right in YASARA on startup.. The aspect ratio of 16:9 is very movie-like, you may have to fiddle with your desktop settings to avoid windows that are too wide to read.. The screen shows very little ghosting, which becomes noticeable mainly in the bottom 5cm.. The 3D Molecular Modeling Cave for 700 EUR.. Recently also.. specialized 3D beamers.. , that previously cost above 10000 EUR, have finally become mainstream technology.. You can now easily build your private molecular modeling showroom, projecting giant 3D views that measure several meters along the diagonal.. The image on the right shows a 3D beamer from Viewsonic, costing around 500 EUR.. The beamer projects the images for left and right eye alternatingly with 120 Hz.. So you additionally need shutter glasses to separate the images, the probably best choice are glasses with DLP-link like the.. Viewsonic PGD-250.. (~80 EUR) or the.. XPAND Edux3.. (~80 EUR).. An alternative with a less comfortable infrared emitter are the.. nuVisionGX glasses.. shown on the right (~200 EUR).. Any beamer that is 3D-ready, features 'DLP-link' and supports a 120 Hz mode over VGA or DVI cable should work with YASARA, to see examples.. click here.. , then select 'Supported 3D projectors'.. Tests have been done in Linux, where you need to add a 120Hz modeline to your xorg.. conf.. Other operating systems work too if they allow you to choose a 120Hz video mode in their display settings.. Additionally, your graphics card must support quad buffered OpenGL stereo, a feature which is normally only available in.. These cards often also have a mini-DIN connector for the shutter glasses, which is however not needed if you chose glasses with DLP-link (see above).. The only disadvantage of DLP-link glasses is that you sometimes need to manually flip left and right image.. At least YASARA Model is required to display stereo.. DTI Virtual Window.. The Virtual Window.. is an autostereoscopic 19" LCD/TFT screen that allows you to see 3D without any additional glasses.. Just press a button to switch between 3D and 2D mode.. Order now from.. Dimension Technologies.. The Virtual Window provides a 3D button, that activates a filter which directs the odd pixel columns to the left eye, and the even pixel columns to the right eye.. So the original resolution of 1280x1024 pixels is reduced to 640x1024 pixels per eye, leading to reduced text quality, just like the Zalman screen above.. Since there are no glasses, the 3D view depends on your position and inverts if the head is moved too far.. The Virtual Window requires at least YASARA Model and a video card that supports quad-buffered OpenGL stereo, e.. NVIDIA Quadro cards.. The Models@Home Cluster System.. Models@Home.. is a distributed computing environment that follows the spirit of the famous.. Seti@Home.. project, but is not tied to a specific application.. Instead you can run all your favourite programs in parallel, without any need to modify or adapt them.. The Models@Home screensaver allows to turn a heterogeneous Windows / Linux network into a uniform cluster.. At the.. , Models@Home is used for most protein modeling tasks, all YASARA force fields were developed with computer power provided by Models@Home.. Models@Home is freely available including the source code.. Click here to download.. click here for more information..

  • Title: YASARA for Android
    Descriptive info: YASARA for Android.. Download now from Google Play Store.. Time is always short in science, and consequently a major focus during YASARA development has always been to deliver your results as quickly as possible.. This goal could be achieved by using PVL, YASARA's custom vector language, that employs MMX/SSE/AVX assembler code.. to deliver a 2x-4x performance advantage.. over normal C/C++ applications.. In 2012, it has finally become possible to carry this performance advantage along to a different world - the world of Android smartphones and tablets.. The credit goes to Intel, who released the Medfield 'system on a chip' (.. in-depth review available here.. ), that empowers smartphones and tablets to execute not only traditional Android apps, but also YASARA's highly optimized MMX/SSE assembler code.. Medfield and its built-in PowerVR GPU are even fast enough to run YASARA '.. as it is.. ', so you do.. not.. get a stripped down app that just happens to share the name with the desktop version, but everything works exactly as you know and expect it, making YASARA the most feature-complete molecular modeling software for smartphones and tablets.. Watch the video on the right to see how we tuned the user interface to guarantee an enjoyable experience also on tiny smartphone screens.. YASARA for Android has been released in April 2013, and requires.. an Intel-inside smartphone or tablet.. If you own an iPhone/iPad,.. please look here for details.. If you are just about to buy yourself a new gadget, consider to choose one from the list below.. There is no extra charge for YASARA on Android.. Intel-inside Android smartphones that can run YASARA:.. Motorola Razr i.. (see video on the upper right): distributed in many countries and therefore easy to obtain,.. e.. from Expansys.. , has been used to port YASARA to Android and has the fastest CPU (2GHz).. It is  ...   RAM, 16GB storage and Android 4.. 0.. can be ordered from us or directly from the manufacturer.. This was the first Android tablet that could run YASARA, with half the CPU power of the Samsung Galaxy Tab 3 above.. Asus FonePad.. : 7" tablet, which is actually a "phablet", since it also works as a mobile phone.. More details at the Asus website.. Asus MeMO Pad FHD 10.. : The resolution of its full HD display is probably too high to be convenient (slows down the graphics since more pixels need to be calculated, some text will be too small).. The following limitations currently apply to YASARA for Android:.. Only the free YASARA View is available from the Google Play store,.. YASARA Model and YASARA Dynamics must be purchased and downloaded from here.. YASARA Structure is currently not available for Android and will probably have to wait until Smartphones with 2 GB RAM are released (Windows 8 tablets have all 2 GB RAM,.. so YASARA Structure runs fine there.. Python plugins are not yet supported.. Ray-tracing with POV-Ray is not possible, since there is no POV-Ray for Android.. But you can save POV-Ray scenes.. The video above shows YASARA running on the.. smartphone, including a molecular dynamics simulation with explicit solvent.. It also gives some general background information about YASARA on Android.. Detailed usage instructions can be found in the second video further below.. , available in India.. , distributed worldwide.. Orange San Diego,.. available in France and the UK.. Ramos W32 tablet.. , providing general YASARA usage instructions and an example for coloring protein surfaces by electrostatic potential using a Poisson-Boltzmann calculation.. Everything works exactly the same on smartphones.. Many thanks to.. Steven Martin.. for guiding through the movies.. The tablet above is the..

  • Title: Why YASARA?
    Descriptive info: Why YASARA?.. Back in 1966, Cyrus Levinthal (known even to first-year biochemistry students thanks to the "Levinthal Paradox" of protein folding) published a clairvoyant article in Scientific American (fig.. 3) that marks the official beginning of molecular graphics and interactive modeling.. Having pointed out the importance of true interaction between the user and the program during modeling (".. it is our experience that an investigator, who is looking at a molecule can frequently understand the reason for a local minimum and by making a small alteration in the structure can return the program to its downhill path.. "), he concluded that by adding pseudo-energy terms to the molecular dynamics force field, we can ".. do the same pulling and pushing in the computer that we can do with our hands while building actual models.. ".. Nevertheless, his ideas have not really made it into todays modeling and molecular dynamics programs.. If you want to know if an Aspartate and a Lysine on the protein surface can form a salt-bridge, you are still often asked to change torsion angles - would it not  ...   whole scene in 3D with.. or a.. stereoscopic TFT screen.. If it is useful - then why do not all modeling programs allow you to do that? The reason is simple: displaying a large protein including surrounding water molecules while running a molecular dynamics simulation - that is still at the edge of what is possible on a single PC today, even with a 3.. 2 GHz CPU.. YASARA therefore makes extensive use of PVL (Portable Vector Language), a new approach to portable high performance computing.. PVL allows us to guarantee highest performance and accuracy.. Check the benchmark page for details.. Fig.. 1: The official start of molecular graphics - back in 1966 at the M.. I.. T.. More details can be found at the.. Max-Planck Institute for the History of Science.. 2: The first YASARA workstation in 1997: Pentium 133, shutter glasses, ultrasonic pointer, virtual reality helmet and force feedback joystick with six degrees of freedom.. 3: Cyrus Levinthal's clairvoyant article from 1966 - most of it is even more valid today than back in these early times of molecular modeling..

  • Title: The YASARA Benchmarks
    Descriptive info: The YASARA Benchmarks.. Since the first YASARA website went online in 1999, we have been providing benchmarks to allow an objective comparison with other programs.. Our goal is however.. to start 'benchmark wars' with other groups, as we are all trying to solve the same problems.. So instead of comparing other programs with YASARA directly, we offer symbolic rewards of 100$ for the first one who can beat YASARA in one of the following benchmarks.. (You do not have to use your own program, just anything you find).. The following restrictions apply:.. Benchmarks are shown for one or more combinations of CPU model, RAM and graphics card.. Your program must be faster on the same or a slower PC.. Your program must be available, you must be able to reproduce your results.. Only the first one who wins a benchmark gets the reward, then the benchmark will be removed.. Benchmark 1:.. 100$.. for a faster molecular dynamics algorithm.. The image on the right shows a classic molecular dynamics benchmark: dihydrofolate reductase (PDB entry 1AOE) and 6875 water molecules, summing up to 23788 atoms.. You can.. download the PDB file here.. Here we measure the time required for one full simulation step of a standard MD protocol using the AMBER03 force field and TIP3P water:.. Find the neighbors within a 7.. 86 Å cutoff distance (usually via a grid-based search).. Calculate the intramolecular (bonds, angles, dihedrals) and shortrange intermolecular (Coulomb, VdW) forces, including the PME shortrange damping function.. Calculate the longrange electrostatic forces using the PME algorithm: interpolate the charges on a grid with 1 Å spacing and 4th order B-splines, perform the two fast fourier transforms and convolution, subtract the longrange component from bonded intraaction partners.. Integrate the equations of motion and move the atoms one step further.. Here are the execution times on various CPU types (single-core only, see next benchmark for multi-core performance).. In our hands, especially the SSE4.. 1 code path is about.. 60% faster than the closest competitor.. (measured in 32bit Linux with standard GCC compiler).. CPU model.. Opteron 265.. Core 2 Duo.. Xeon L5420.. Code path.. 3DNow! + SSE + SSE2 + SSE3.. SSE + SSE2 + (S)SSE3.. SSE + SSE2 + (S)SSE3 + SSE 4.. 1.. CPU cycles.. 292.. 91 million.. 231.. 78 million.. 189.. 95 million.. Actual time.. 0.. 1627 seconds @ 1.. 8 GHz.. 1073 seconds @ 2.. 16 GHz.. 07598 seconds @ 2.. 5 GHz.. Notes:.. How the results above translate to.. simulated nanoseconds per day.. depends on the chosen timestep and thus the accuracy/performance tradeoff you are willing to take.. If bonds to hydrogen atoms are constrained and rigid water molecules are used, YASARA reliably reaches a timestep of 4 femtoseconds.. Benchmark  ...   provides a very accurate view of protein structure.. Running a molecular dynamics simulation of such a crystal moves the protein away from where it should be, due to inaccuracies in the force field.. The smaller the damage, the more accurate the force field.. During a 1 nanosecond simulation with YASARA's YAMBER2 force field, the maximum Calpha RMSD from the true structure is 0.. 70 Å.. 100$ are yours if you manage to obtain a lower RMSD with any MD program / force field you like, under the condition that you did not optimize the force field specifically for 2A0B or its homologues.. Hydrogens have been added with WHAT IF's H-bond network optimizer, counter ions and disordered water molecules were placed by YASARA.. The cell size is 30.. 456 x 34.. 924 x 110.. 741 Å, you can.. download a PDB file here.. Simulations must be run at the temperature of experimental structure determination (277K).. Save snapshots in intervals of 5ps and calculate the average Calpha RMSD for all four chains.. This average must stay below 0.. 70 Å in all 200 snapshots to win the benchmark.. Benchmark 4:.. for better molecular graphics.. The screenshots on the left show PDB entry 1N8R, the 50S ribosomal subunit with 98569 atoms, in space-filling mode.. In the upper image, all atoms are on screen, YASARA delivers either 10 frames per second without shadows (many programs are a factor 35 slower), or 5.. 5 frames per second with shadows calculated in real-time (as shown).. On the lower image, we flew right through the ribosome to the backside, most atoms are now off-screen, resulting in 106 frames per second without shadows (as shown).. To win the 100$, your program must be faster in both cases (either with or without shadows), while reaching at least the same visual quality (e.. spheres must be equally round), and it must run on the same or a slower system.. Benchmark system:.. Opteron 265 single-core @ 1.. 8 GHz,.. Window size 1024x768, color depth 32 bits, nVIDIA Geforce 6600 graphics card.. Benchmark 5:.. for faster interactive molecular dynamics.. Interactive molecular modeling during a real-time molecular dynamics simulation allows you to pull individual atom and entire molecules around with the mouse or 3D input devices.. The image on the right shows the simulation of dihydrofolate reductase (see benchmarks 1 and 2 above for details), including all water molecules.. Using four CPU cores on the system described below, YASARA reaches 12 frames per second, i.. 12 molecular dynamics steps and 12 screen updates including real-time shadows.. To win the 100$, your program must be faster on the same or a slower system and reach at least the same visual quality.. Opteron 265, four cores @ 1..
