Hi PremPrakash, In the Tools menu, see under Structure Analysis: - Distances (for measuring distances) - Angles/Torsions (for measuring angles defined by 3 atoms and torsions defined by 4 atoms) Clicking the Save button on these tools will save the measurements to a text file. How to make the measurements and other details are given in the manual page: http://www.cgl.ucsf.edu/chimera/1.2199/docs/ContributedSoftware/ structuremeas/structuremeas.html The text file of saved measurements is not in formats you mentioned, however. It sounds like you are trying to make input to some other program. You would have to take those measurements and reformat them as needed for that other program. I hope this helps, Elaine On Sep 28, 2006, at 4:41 AM, Prem Prakash Pathak wrote:

Hi! I am using the chimera for the visualizing protien form *.pdb file. I wanted to get the nonbonded distance , *.upl file and angle constraint files. Would you please help me in solving the problem.
