Rosetta Commons Black Lives Matter Statement

Trigger warning: mentions acts of violence and racism
We, as members of the Rosetta Commons, recognize the grief and frustration of many members of our community and reaffirm our commitment to the safety and dignity of Black lives.

There’s another one called “strand_fail.mov” that looks like this:



What each of these movies show is a failed initial attempt at extending the parametric bundle design methods used in Rosetta. A little while ago, Vikram Mulligan and I sat down to think about what would be needed to describe a β barrel. We started off noting that a strand could be thought of as a helix in which every residue flips 180º, and that we would need to describe a “squishing” parameter to describe non-circular barrel systems.
Vikram recently moved on to the Flatiron Institute in New York, but this was a fun little project that kind of went nowhere so I thought I would share it here. A…
