Byexample synthesis of architectural textures

This additional material first shows more synthesis results in Section 5 and give further details and illustrates the way our synthesised textures are filtered in the GPU fragment shader in Section 1 While the main paper gives a complete description of our system for synthesizing architectural textures, there is also a number of small algorithmic improvements that build on the special nature of our problem and provide a faster implementation. We describe them here, since they are not specifically related to the core of our synthesis system. They deal with Dijkstra’s algorithm (Section 2, page 1), the integration of a histogram computation into Dijkstra’s algorithm’s inner loop (Section 3, page 3) and the fast construction of the graph G (Section 4, page 4). Many notations that are used here are defined in the main paper and not redefined here. Please refer to the paper for their definition.

A User-Friendly DNA Modeling Software for the Interpretation of Cryo-Electron Microscopy Data.

The structural modeling of a macromolecular machine is like a "Lego" approach that is challenged when blocks, like proteins imported from the Protein Data Bank, are to be assembled with an element adopting a serpentine shape, such as DNA templates. DNA must then be built ex nihilo, but modeling approaches are either not user-friendly or very long and fastidious. In this method chapter we show how to use GraphiteLifeExplorer, a software with a simple graphical user interface that enables the sketching of free forms of DNA, of any length, at the atomic scale, as fast as drawing a line on a sheet of paper. We took as an example the nucleoprotein complex of DNA gyrase, a bacterial topoisomerase whose structure has been determined using cryo-electron microscopy (Cryo-EM). Using GraphiteLifeExplorer, we could model in one go a 155 bp long and twisted DNA duplex that wraps around DNA gyrase in the cryo-EM map, improving the quality and interpretation of the final model compared to the initially published data.journal article2017importe
