YASARA Development News

NOTE that this page is only updated sporadically. Better click here to access the detailed list of new features, which are released on a weekly basis.

February 2022 The PetWorld database, a collection of gigastructures for interactive exploration has been released at www.PetWorld.vision. Contribute your own models and get all YASARA stages free of charge.
January 2022 YASARA can build entire genomes (single- and double-stranded DNA or RNA), taking as input the FASTA sequence and a collection of nucleic acid binding proteins. Proteins are attached automatically to their binding sites.
December 2021 The new facilities for building gigastructures have been used to construct a SARS-CoV-2 model which can be explored interactively.
November 2021 YASARA can shrink molecules to a coarse-grained representation made of "pet atoms".This reduces the atom count by about a factor of 50 and speeds up construction and MD simulations of giant systems.
October 2021 A new packing engine to build gigastructures with billions of atoms is available. Compartments can be defined with polygon meshes and filled with proteins inside, outside and on the boundary (in this case usually including membrane fragments). The packing can be done using pet atoms (see above) to complete the task quickly.
August 2021 YASARA includes the OpenH264 MPEG4 encoder to save high quality movies with high compression.
June 2021 YASARA's Vulkan graphics engine has been improved to calculate per-pixel ambient lighting, yielding a better 3D appearance.
December 2020 YASARA enters the billion atom world. Identical copies of object (instances) can be created for visualization, while the number of atoms in the soup remains unchanged. The new Vulkan/Metal graphics engine can display these instances so quickly that interactive visualization of systems with billions of atoms in all common styles from balls and sticks to ribbons is now possible.
October 2020 YASARA calculates and shows contact surfaces, the help movie 'Surfaces II' has been updated to include the new, easier approach
July 2020 After nearly 30 years of service, OpenGL has reached the end of its lifetime as the top API for cross-platform 3D graphics. Its successor is called Vulkan and delivers more performance, control and flexibility. The YASARA graphics engine has been rewritten from scratch for Vulkan and now delivers in real-time what you previously only got from POVRay via slow ray-tracing (e.g. contact hardening soft shadows for improved depth perception). In MacOS, YASARA now uses the Metal API, since OpenGL is deprecated there.
