Please disregard my previous message. I realized that the reason I got
the error was because I had not loaded in the amber force field yet.






Hi everyone,

    I am following the antechamber tutorial and I am using amber9.

I have created "sustiva.frcmod sustiva.prepin" according to the
tutorial and loaded them in xleap. When I tried to solvate the molecule
using the command "solvateOct SUS TIP3PBOX 10" I got the following
message. Why is it complaining like that?


Loading parameters: /home/tlwin/local/amber9/dat/leap/parm/gaff.dat

Reading title:

AMBER General Force Field for organic mol., add. info. at the end (June,

Loading parameters: ./sustiva.frcmod

Reading force field modification type file (frcmod)

Thank you in advance,
