The currently released Chrome web browser comes with built-in functionality to take a screenshot of webpages without any add-ons. It allows taking a high-quality screenshots at high resolutions. Types of Screenshots The Chrome browser support taking 4 types of screenshots of a web page. Capture area screenshot - taking screenshot on specific region Capture full size screenshot - taking scrolling screenshot from top to bottom Capture node screenshot - taking screenshot of a specific HTML element Capture screenshot - taking full screen screenshot The Capture full size screenshot / Capture screenshot options are accessible via Chrome's developer tools (Ctrl+Shift+I). Furthermore, Capture area screenshot / Capture node screenshot options are accessible via Run command (Ctrl+Shift+P) by entering command “ screenshot ”.

Protein-Ligand Binding Site Analysis using Chimera

Chimera (or UCSF Chimera ) is an interactive molecular visualization and analysis program developed by the Resource for Biocomputing, Visualization, and Informatics ( RBVI ) at the University of California, San Francisco ( UCSF ). ChimeraX (or UCSF ChimeraX ) is the next-generation molecular visualization program, which is a successor of Chimera. The Chimera/ChimeraX program supports analyzing various molecular structures and related data, including sequence alignments, docking results, molecular assemblies, electron density maps, trajectories, and conformational ensembles. It can be downloaded freely for academic, government, nonprofit, and personal use. Protein-Ligand Interaction Models In the protein-ligand interaction model, proteins or ligands are represented by a wire-frame model / stick model / ball-and-stick model / cartoon model / space-fill model / surface model, but not both. The interactions between protein and ligand atoms is represented by dotted or dashed lines. T
