@joshdcryoem.bsky.social will also be giving a talk about his prior work as a PhD student with Chris Russo developing strategies to take advantage of the reduced radiation damage at liquid Helium temperatures for cryo-EM. You can find their paper here: www.pnas.org/doi/abs/10.1...

In the Bay Area? Love computational cryo-EM/ET?

Come join us for the first edition of FrostByte - a meeting for the local computational cryo-EM methods community!

Thanks to @joshdcryoem.bsky.social and Ariana Peck for help organizing!

For a shorter read, @mrclmb.bsky.social and @science.org also have articles about the helium story. www.science.org/content/arti...

After years parked at a Polara, I’m excited to share that my PhD work is finally out! We figured out why imaging at liquid helium temperatures wasn’t working—and how to fix it.

A new statistical metric for robust target detection in cryo-EM using 2D template matching A novel statistical metric for 2D template matching (2DTM), the 2DTM p-value, has been developed to improve the detection of targets in cryo-EM images under various imaging and sample conditions, particularly for smaller and aspherical targets.

It should be relatively simple with the Bio.PDB package in Biopython. It has both pdb and mmtf IO modules.
