Welcome to gRINN’s documentation!

gRINN is a software for residue interaction enery-based analysis of protein MD simulation trajectories.

Current version is v1.1.0.hf1.

Start with the Tutorial.

News

2026/01/12: After a long(!) hiatus, gRINN is back! Please visit the i-gRINN web service at https://grinn.bio-cloud.site to use the new version. This website is NOT maintained anymore - the original version offered here may not work with recent versions of gromacs and namd2 as well as Ubuntu/Mac OS. We highly recommend using the new version.

2018/11/27: Thank you for your interest in gRINN! We greatly appreciate your feedback. We’re aware of several bugs, including incompatibility with some input data and gromacs versions, We’re currently working to fix them in the next version release (anticipated January 2019). If you also experience problems, please feel free to send an email to onursercin AT gmail DOT com!
