The EMDataBank Validation Challenge was a challenging task for students newly introduced to the cryoEM and molecular modeling fields. Cosmonautica cheat. However, the competition provided an effective space for student modelers to discover and explore the potentials of atomic modeling and refinement by practicing on published atomic structures. Here, by employing manual molecular modeling programs such as Coot, Phenix, and Chimera, we have regularized and improved three targets.

Atomic Space Command is space sim game by Ocean Quigley (No You Shut Up Games). Players can builds ship by themselves or with friends, fly ships into combat and dominate the solar arena. Additionally, the CFSCC executes tactical control over globally dispersed Air Force, Army, and Navy space units that command ground-based space capabilities and satellites in every orbital regime. CFSCC is co-located with the 14th Air Force and the Combined Space Operations Center at Vandenberg Air Force Base in California.

The T20S proteasome and TRPV1 ion channel allowed us to broaden our understanding of these modeling techniques while the 70S ribosome served as a challenge to test the limits of our abilities. We were successful in our efforts to improve each of the models and provide here our cohesive methodology for de novo modeling with and without homology models, which may serve as a starting point for other undergraduates and researchers just entering the realm of cryoEM. Additionally, we provide some constructive criticism to facilitate the introduction of said undergraduates and researchers into cryoEM in the future. Previous article in issue. Next article in issue.
