Hello everyone,
Thanks very much for your reply on the partial charge calculation of lipid membrane.
I intend to get the partial charges with RESP after optimization with Gauss. However the output of Gauss for the lipid (dppc) differs a lot from the input conformation which is one molecular of the pre-stabled lipid membrane (I intend to attach the file behind but failed).
So I want to ask: which file should I use in RESP, the input (one of the lipid molecular in a equilibrated lipid membrane) or the output (optimization of the input HF/6-31G*)?
What is more I get the partial charges of both the input and output confirmations of dppc with AM1-BCC, which is of cause a little different between them. Again I am wondering which one to use in my MD stimulation.
Thanks again
