Dear Boaz, The archimboldo model gives Rot z-score: 8.1, Trans Z-score 13.8
Not sure this matters, as it lacks a few loops that even good old arp/warp can fill up in ten minutes ;-) A.

The accuracy it demonstrated compared to others is excellent. “Our” target (T1068) that was not solvable by MR with the homologous search structure or a homology model (it was phased with Archimboldo, rather easily), is easily solvable with the AlphaFold model as a search model. In PHASER I get Rotation Z-score 17.9, translation Z-score 26.0, using defaults. imho what remains to be seen is: a. how and when will a prediction server be available? b. even if training needs computing that will surely unaccessible to most, will there be code that can be installed in a “reasonable” number of GPUs and how fast will it be? c. how do model quality metrics (that do not compared with the known answer) correlate with the expected RMSD? AlphaFold, no matter how impressive, still gets things wrong. c. will the AI efforts now gear to ligand (fragment?) prediction with similarly impressive performance? Exciting times. A.

A quick look suggests that a lot of the test structures were solved by phaser or molrep, suggesting it is a very welcome improvement on homology modelling. It would be interesting to know how it performs with structures of new or uncertain fold, if there are any left these days. Without resorting to jokes about artificial intelligence, I couldn't make that out from the CASP14 website or the many excellent articles that have appeared. Best wishes, Jon Cooper.

I am wondering how the labs will have access to this technology in the future (would it be for free coming from the company DeepMind - Google?). It seems that they have already published some code. Well, exciting times.
