[phenixbb] d99 resolution measure availability?

[Oliver Clarke]

Hi,

I think the “d99” criterion described in this preprint (https://www.biorxiv.org/content/early/2018/03/14/279844) looks like a really interesting FSC-independent way to measure res in real space, and I’d like to give it a go on my maps (particularly those where I am suspicious of the FSC-based res based on map appearance, or where I suspect overfitting).

Is it available in any phenix package at present? The scripts site mentioned in the preprint (http://phenix-online.org/phenix_data/afonine/cryoem_validation/) is currently rather sparsely populated.

(Also, I wonder whether a directional version of the d99 criterion might be useful to estimate anisotropic res in the case of a preferred orientation, analogous to the 3D-FSC approach of Yong-Zi Tan and Dmitry Lyumkis?)

Cheers
Oli
