Dear Bulletin Board,

The correct answer came from Ashley Pike (see below). Moleman2 calculates 
indeed exactly the values our reviewer wants to see! There must be some Uppsala 
connection here….

Best regards,
Herman

Hi Herman,
As you state MOLEMAN2 from the USF package will give these…it is old but 
linux/mac distribution still work and is easy to install…

read in pdb file and then type ‘bf bo’ and all values you state are printed out 
– this is the only software I am aware of that gives these values so I guess 
the reviewer is a moleman/moleman2 user fan!

Subject: [ccp4bb] r.m.s.d. ΔB

Dear Bulletin Board,

A referee wants for the “Table 1” in the supplementary information the 
following data:

The r.m.s.d. ΔB (bonded atoms) (Å2)
All protein atoms
Main chain – Main chain
Side chain – Side chain
Main chain – Side chain

r.m.s.d. ΔB (Non-bonded contacts) (Å2)
All protein atoms

Using google I found at that some of these numbers could be calculated with 
Moleman, although I am not sure to what extend this program is still maintained.
Older versions of Refmac would calculate r.m.s.d. ΔB’s for main chain and side 
chain bonds, which I guess would be the “Main chain – Main chain” and “Side 
chain – Side chain” values requested. However, what would should I think of the 
“Main chain – Side chain” values; differences between Calpha and Cbeta atoms?

What would be the use of these numbers? The standard CCP4 validation programs, 
or any validation program I know, do not calculate these numbers, so they do 
not seem to be extremely important. If somebody could point me to a program 
which could calculate these number without too much effort, I would be happy to 
do it.  Otherwise, I would still be willing to go the extra mile if someone 
could convince me that it is useful to have these numbers.

Thank you for your help!
Herman
