Schrödinger Software Release Overview

Schrödinger announced their software release 2020-2, which is available for download now. This quarterly release includes usability improvements and performance enhancements across all of their software offerings.

What is Schrödinger used for?

Schrödinger develops state-of-the-art chemical simulation software for use in pharmaceutical, biotechnology, and materials research. Their physics based computational platform leverages a deep understanding of physics, chemistry, and predictive modeling to accelerate innovation in drug discovery. This allows collaborators to discover high-quality, novel molecules more rapidly, at lower cost, and most likely with a higher likelihood of success compared to traditional methods.
