Hi Lei,
It sounds like there is something messed up with your .leaprc file. Would it
be possible for you to post the contents of this file.
The leaprc files in $AMBERHOME/dat/leap/cmd were created to load the correct
library and parameter files for each of the different force field
combinations. You can create your own .leaprc file to load whatever you want
but what I tend to do is use the ones provided, e.g leaprc.ff99, and then
manually load my own extra library files (using loadoff) and parameter files
(using loadamberparams) once leap is running. This way it avoids any
confusion that can arrise from editing the 'default' files.
If you can send me a copy of your leaprc file and the pdb file from which
you are trying to create the prmtop file I can take a look here and see if I
can get it to work.
All the best
Ross
