Yes, I got this type of problem also. It appends because you forgot to
define a new atom type, or because a leap command arrives after
(instead of before) another one...
See below the script, it worked for me (no error message):
--------------------------------------
source leaprc.glycam04 # or any other force field
addAtomTypes {
{ "CA" "C" "sp3" }
{ "HA" "H" "sp3" }
}
FRCMOD = loadamberparams frcmod.cd
--------------------------------------
On the contrary, with the 2nd script below, I get a similar error than
the one you reported:
--------------------------------------
source leaprc.glycam04 # or any other force field
FRCMOD = loadamberparams frcmod.cd
addAtomTypes {
{ "CA" "C" "sp3" }
{ "HA" "H" "sp3" }
}
--------------------------------------
