Dear all,

As an output of MOE db I get data for all conformations of molecule in a single file. Each molecule is presented like this:

<TRIPOS>MOLECULE
NONAME

USER_CHARGES

What I need for Gaussian input is to get numbers of atoms(3-rd line, 28 for this case) and get 2,3,4 columns after @<TRIPOS>ATOM - line. I realise it should be easy, but I have just started using awk, so still I am not so good in syntax. This could actually make my work easier, so I ask you to help me with finding ways to do this. Thanks.
