Hi all, I want to know if there is any server/software which does the PDB based (structure based) fold recognition. All I got for fold prediction are sequence based. I am asking this because what if I have a novel sequence and I got the crystal structure of that protein but I don't know what kind

Dear Emily, In this case, I was referring to the difference between 1065 obtained placing 4 copies of the monomer and 722 obtained placing 2 copies of the dimer. A difference of over 300 is substantial when we feel that an increase of 60 is enough to be reasonably convinced that a solution for

Yes, I can see how that message would be confusing! This comes from a new feature. Phaser now does a relatively liberal packing test as part of rescoring the fast translation results with the full likelihood function. Peaks that are rejected at this stage aren’t counted for the top peak heigh

Regarding the warning message "The top solution from a TF rescoring did not pack”, I get this on all the PHASER jobs that I have run recently, but looking through the PHASER log file I cannot see any evidence for packing failure. It may be that the failure is buried in an obscure place in the ve

You need to provide a bit more information. First of all about the data processing.. Is the space group correct? ways of being misled are: Non-crystallographic translations with a shift of ~0.5 along an axis - say a. This will generate absences in the odd h 0 0 reflections and can make the space
