EM Methods

Our most recent work has focused on developing an tools that make it possible for cryo-EM users to easily access the computational capabilities in the cloud.

We began by creating an environment within Amazon Web Services (AWS) where users could create their own computer clusters to process cryo-EM data. The flexibility of this "pay-as-you-go" approach can be particularly helpful to new labs that don't have their own clusters or easy access to high-performance computing resources.

Most recently, we developed a set of tools that submit data processing jobs to AWS directly from the user's local computer or laptop, without requiring the user to interact with AWS itself. This platform also allows users to submit Rosetta modeling building jobs to AWS. This work is now being led by Mike Cianfrocco, a former postdoc in the lab, in his own group at the University of Michigan.
