[phenixbb] measuring angle

Hi,

Could you please tell me how I can measure angle between two helices. Can
COOT or PYMOL measure this?
I have another question.

In PDBSET, I can use CHAIN command in shell script to write a pdb file with
a desired chain ID. What is the command
 in shell script to write a pdb file with a desired SEGID? As for example:-

pdbset xyzin start.pdb xyzout end.pdb <<eof >& pdbset.log
ROTATE [INVERT] [MATRIX] values
CHAIN A
end
eof

This will change the chain ID to A after rotation. But, I also like to give
a segid in the end coordinate.

Thank you in advance and have a nice THANKS GIVING WEEKEND

Hena
