Welcome to the GROMACS (.gro) File Viewer, a specialised web-based tool for researchers, students, and computational biologists to inspect molecular structures. GROMACS is a powerhouse in molecular dynamics, and its ASCII-based coordinate files (.gro) are fundamental for setting up and analysing simulations. Our viewer removes the need for heavy desktop software or complex command-line tools by offering an instant, browser-based environment to verify your system’s coordinates, residue numbering, and box dimensions with precision and ease.
This tool is built for speed and accessibility, letting you drag and drop your files to visualise the molecular layout in three dimensions immediately. Beyond visualisation, the viewer parses critical metadata, including atom names, residue types, and velocity vectors, so you can audit your simulation inputs for errors before committing to long compute runs.
