  Hi Priit,

two steps:

1) Select the domain (region) in question, say it is chains A (residues 
from 1 to 1000) and B (all residues):

phenix.pdbtools model.pdb keep="chain A and resseq 1:100 or chain B"

2) Take new PDB file created at step "1)" and run

phenix.pdbtools model_new.pdb --show-adp-statistics

which will give you exactly what you want and more!

Let me know if you have any questions or problems or if I can be of any 
more help!
