Keep CHARMM-GUI Free for Scientists Worldwide

Dear CHARMM-GUI Community,

I am writing to you not only as the developer of CHARMM-GUI, but as someone who has spent many years building and maintaining this resource for the scientific community. I need your help.

CHARMM-GUI now supports more than 70,000 users in more than 9,000 institutions from more than 140 countries worldwide. Every day, researchers rely on it to prepare complex molecular systems, accelerate simulations, and enable work that would otherwise take far more time and effort. For many groups, it has become a critical part of their research workflow. For many universities, it has been used as an essential tool for teaching. We also see fast-growing numbers of publications using CHARMM-GUI: Google Scholar Citations.

Since 2006, our team has continuously worked to expand capabilities, improve reliability, and respond to the needs of a rapidly evolving field. We maintain and update the platform, integrate new methods, support users, and ensure that it remains freely accessible. This has been a sustained effort — and one we are proud of. But we have reached a critical juncture.

The infrastructure currently supporting CHARMM-GUI is no longer sufficient for the scale of usage we are seeing. Without an upgrade, users will begin to experience slower performance and reduced availability, directly impacting ongoing research and teaching across many labs and universities worldwide.

If CHARMM-GUI has been part of your research, I ask you to consider supporting this effort. This is a direct investment in the continuity of a resource that many of you depend on. It will allow us to maintain performance, reduce interruptions, and continue supporting the scientific community that relies on CHARMM-GUI. Here is how you can help:

  • Contribute online: Click the "Give Now" button to be directed to a secure giving page. Contributions at any level make a difference.
  • Become an organizational sponsor: Sponsors will have their logo prominently displayed on the CHARMM-GUI website for 12 months in recognition of their support. The sponsorship level is $5,000. Payment may be made online or by check. Please email your logo to Lisa Szydlow at lhs223@lehigh.edu.
  • Give by check: Please make checks payable to Lehigh University with "CHARMM-GUI Support" or "CHARMM-GUI Sponsor" in the memo line, and mail to:

To make a contribution using institutional resources or grant funds, please contact Natasha de Luna, Associate Dean for Development, Lehigh University College of Arts and Sciences, at nlg222@lehigh.edu.

We have built CHARMM-GUI as a resource for the community. With your support, we can ensure that it continues to serve students, researchers, scientists, and practitioners around the world.

Sincerely,

The CHARMM-GUI has done more than any other software infrastructure in the world to democratize and support the usage of advanced molecular dynamics calculations to study biomolecular systems.
— Benoit Roux, University of Chicago
CHARMM-GUI is a transformative platform that enables us to build models of complex biomolecular systems with speed, reliability, and reproducibility. Its ease of use removes technical barriers, supporting both expert researchers and students learning the fundamentals of biomolecular simulation. In our group, it has become an essential tool for multiscale simulations, from coarse-grained to atomistic models of micelles, membranes, and protein assemblies. Continued development of CHARMM-GUI will further expand access to these capabilities and accelerate discovery across the biomolecular sciences.
— John Straub, Boston University
CHARMM-gui plays major roles in both teaching and research. It makes molecular simulations broadly accessible to students of different backgrounds, and greatly facilitates the setup of highly complex molecular simulations for both biomolecular and materials research. It also ensures reproducibility of complex simulations, and promotes best practices in multiscale computations.
— Qiang Cui, Boston University
The CHARMM-Gui is an essential resource for computational chemistry and biophysics that facilitates the preparation of complex molecular systems and the application of a range of methodologies to those system. It has greatly expanded the use of the CHARMM additive and Drude polarizable force fields developed in our lab.
— Alex MacKerell, University of Maryland
We need to upgrade our servers, and to do so, we are working to raise $150,000 by July 15.
