Dear Amber users
I ran antechamber to parameterize my molecule consists of 354 atoms.
It is the organic molecule which has long aliphatic branches at one side
and molecular
rod with successional phenyl rings.
Next was my antechamber command...
------------------------------------------------------------------------------
./antechamber -i nano.mol2 -fi mol2 -o nano.prepin -fo prepi -c bcc -s 2
-nc 0 -j 5 -rn DUM
------------------------------------------------------------------------------
after processing, i could get some messages and nano.prepin file.
messages from antechamber processing was..

------------------------------------------------------------------------------
as you see, in nano.prepin file, there were six unrecognized atomic names
I thought that they are dummy atoms which might be treated manually.
but i don't know which atom is correct instead of dummy
and Xleap can't load nano.prepin because of dummy atoms.
Question 1. It's possible to treat dummy atoms manually? then how?
Question 2. Can the antechamber parameterize the unusually long organic
molecule
like mine?
Please tell me....T.T
Thanks
