sam,
since this question has nothing to do with
the subject of the mail you are replying to,
please repost your mail, with a proper subject.
people that have to go through a lot of mail
use subject lines an mail-id (you can't see them,
but they are in the mails) to presort mails into
groups and look only at those where the topic
is interesting.

what do you mean by not recongnize? VMD does not care at
all how you name your atoms...
please elaborate a little more.
