Subject: AMBER: Antechamber/Leap, problem with Improper angles

Dear Amber list,

I have a problem using antechamber/Leap on some ligands, especially when
it comes to assign improper angles. All the necessary files are attatched.

- When I run antechamber (distribute with amber 8):
"antechamber -nc 0 -rn lig -i tobeconvert.mol2 -fi mol2 -o lig_bcc.prepi
-fo prepi -c bcc -j 4 -at gaff -pf y"
"lig_bcc.prepi" indicated 15 improper angles.

- When I run parmchk:
"parmchk -i lig_bcc.prepi -o lig_bcc.frcmod -f prepi"
"lig_bcc.frcmod" just shows 4 additional dihedral angles ...

when running Leap with the following script:
"source leaprc.gaff
mods = LoadAmberParams lig_bcc.frcmod
LoadAmberPrep lig_bcc.prepi
saveAmberParm lig lig_bcc.prmtop lig_bcc.prmcrd
quit"
"lig_bcc.prmtop" shows 12 improper angles (negative value of the 3th
dihedral angle) instead of 15 as in "lig_bcc.prepi".
the one I particularly miss is "C2 C4 C3 O1" which should be planar.

***So my first question is why 12 improper angles with Leap when
antechamber defined 15.
***My second question is that I am not really sure about how to
interpret the Leap log file "leap.log".
Did Leap find only 1 improper angle only ? why there is 12 improper
angles in "lig_bcc.prmtop" than ?
please have a look at it in the following line from the "leap.log" file.

Any suggestions ?

Thanks a lot for any help.
