Hey,
I have thought about it but I always postpone it since you have to fax the confidential agreement. I don't even know if we have a fax machine at work!

Ämne: Re: AMBER: ptraj, hbond and non-bonded contacts
Dear Sam,
did you try the ligplot program?
homepage -
http://www.biochem.ucl.ac.uk/bsm/ligplot/ligplot.html
SH2 domain complexed with a peptide containing phosphotyrosine (1sha) -
http://www.biochem.ucl.ac.uk/bsm/ligplot/manual/examples/p1sha_c.html
The program generates a text file, which includes the interaction, as well.
Hope this helps
