Read more about the philosophy behind YASARA.

System requirements: None, please download the free YASARA View to verify that YASARA runs on your computer (and please contact us if you encounter problems). Hints for high molecular dynamics performance are available.

Stage I: YASARA View - Free download

YASARA View is available for free and contains all the functions you need to explore a macromolecular structure interactively. As a bonus, you get YASARA's innovative 3D engine, which is up to 10 times faster than what you usually know from Vulkan and OpenGL, you can load thousands of structures at the same time, move them around independently, create publication-quality ray-traced images including labels, and program your own macros and Python plugins. Included is YASARA Movie, a player for multimedia presentations and tutorials created with any of the higher stages, as well as the YASARA Python module to simply 'import yasara' in your Python scripts.

Stage II: YASARA Model - free for academic users

YASARA Model

YASARA Model contains YASARA View and adds all the functions you need to explore, analyze and model small to macromolecules in a production environment. This includes many features you often miss: unlimited undo/redo, macro recorder, virtual reality, quad-buffered stereo with shutter glasses or stereoscopic screens. You can create multimedia presentations (YASARA Movies), which can be encoded as MPEGs and pasted into Powerpoint or played back with all stages of YASARA, including the free YASARA View.

Key features:

YASARA Model is free for academic users and costs 600 € / 690 $ for commercial single users, including one year of support and updates. The commercial price includes Windows, Linux and Android, MacOS may cost extra, a license for the entire research group costs 100% extra. Delivery is via download link. Customers in Austria and customers without VAT-number in the EU have to add 20% VAT.

Stage III: YASARA Dynamics

YASARA Dynamics

YASARA Dynamics contains YASARA Model and adds support for molecular dynamics simulations. In addition to YASARA's own force fields (NOVA, YAMBER) you can use other well known MD force fields like AMBER, and run accurate all-atom MD simulations in aqueous solution with Particle Mesh Ewald longrange electrostatics. YASARA Dynamics is not a "black box" with input and output files, but shows the MD simulation in real-time on screen. You can fully interact with the scene, pull atoms or whole molecules around and finally do the type of molecular modeling that Cyrus Levinthal already pioneered back in 1966 ("..do the same type of pulling and pushing in the computer that we can do with our hands while building actual models. ", cited from an article in Scientific American).

Key features:

YASARA Dynamics costs 300 € / 345 $ for academic and 2400 € / 2760 $ for commercial single users, including one year of support and updates. This price includes Windows, Linux and Android, MacOS may cost extra, a license for the entire research group costs 100% extra. Delivery is via download link. Customers in Austria and customers without VAT-number in the EU have to add 20% VAT.

Stage IV: YASARA Structure

YASARA Structure

YASARA Structure contains YASARA Dynamics and adds all the functions needed to predict and validate macromolecular structures, including ligand docking and highly accurate force fields with knowledge-based potentials. If you already own one of the other YASARA stages, you can upgrade easily, just contact us for a quote.

Key features:

YASARA Structure costs 410 € / 471 $ for academic and 3600 € / 4140 $ for commercial single users, including one year of support and updates. This price includes Windows and Linux, MacOS may cost extra, a license for the entire research group costs 100% extra. Delivery is via download link.

YASARA NMR Module

The YASARA NMR Module solves protein structures at the touch of a button, based on the protein sequence and distance-, dihedral-angle and RDC restraints. Input files are compatible with X-PLOR, folding and refinement are visualized in real-time on screen, allowing to identify problematic restraints. Floating assignments and non-standard residues are supported, all the details are described here.

3DM - the protein superfamily data integration platform

The Bio-Prodict 3DM information systems are protein super-family platforms that collect, combine and integrate many different types of protein-related data. 3DM systems are designed to facilitate the exploration of sequence-structure-function relations, and have successfully been used many times to elucidate the function of individual amino acids, predict the effects of mutations, among others.

The 3DM platform is developed and distributed by Bio-Prodict, a CMBI spin-off company like YASARA Biosciences. Please contact for details and pricing information. An introductory movie can be watched at the Bio-Prodict site, more details about YASARA integration are available here.


The WHAT IF / YASARA Twinset

Twinset

The Twinset is a customized joint-distribution of WHAT IF and YASARA Dynamics or YASARA Structure (currently Linux and Windows only). With over 5000 citations, WHAT IF is a widely used program for structure validation and modeling. In the Twinset, WHAT IF inherits YASARA's user interface, graphics engine, macro language, unlimited undo/redo etc, so that WHAT IF functions become easily accessible.

The Twinset is freely available, but you need licenses for YASARA Dynamics or YASARA Structure. Customers in Austria have to add 20% VAT.

To order the Twinset, just place a normal order for YASARA Dynamics or YASARA Structure and then request the Twinset upgrade from support. If you already own YASARA, email us your YASARA serial number.


The FullHD/4K 3D cinema starting at 400 EUR

3D Molecular modeling cave

During the past years 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 the 3D beamer Optoma UHD40, which cost around 1200 EUR when it was introduced. In the mean time, prices for "3D ready" beamers have dropped to 400 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, and they must support the DLP-link signal sent by the beamer. There are countless glasses available, prices start at 20 EUR, inside the EU we can recommend the Pulox glasses.
Notes: The Optoma UHD40 and HT3800 beamers have been tested in Linux and Windows. Especially in Linux the installation is non-trivial, but we prepared detailed instructions for all owners of YASARA Model+, please contact us. Your graphics card must support quad buffered OpenGL stereo, a feature which is normally only available in workstation products like nVIDIA RTX and AMD FireGL. At least YASARA Model is required to display stereo.


The 3D molecular modeling lab for 250 EUR

3D Molecular modeling lab

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. Later follow up models included the LG D2342P, the HP 2311x, the AOC e2352Phz or the Viewsonic V3D231. Unfortunately all have been discontinued, so screening second hand sites like Ebay is currently the only option. The big advantage is that this type of display is directly supported by YASARA with any graphics card and any operating system (no expensive workstation cards or special video drivers are needed). You can move your molecules through 3D space using the Connexion 3D SpaceMouse with six degrees of freedom. Order now for 50 EUR.


The Models@Home cluster system

Twinset

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 CMBI, Models@Home was used for many 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.
