Hello Tang Kwa,
Junmei Wang used to have a tutorial on his web page but the link is not
working now.
The format of mainchain.dat is as follows: you specify head, tail, and
mainchain atom names. Then the capping atoms
you don't want to have in the prepin (omit). Then AMBER atom types before
and after head and tail, resp (in order to determine dihedrals). Last comes
charge of the resulting fragment.

Hope this helps,

Martin
