 Good morning everyone,

I created a tleap.in file and wanted to run it but it keeps giving me the
syntax error or

-I: Adding /mnt/d/amber/amber18/dat/leap/prep to search path.
-I: Adding /mnt/d/amber/amber18/dat/leap/lib to search path.
-I: Adding /mnt/d/amber/amber18/dat/leap/parm to search path.
-I: Adding /mnt/d/amber/amber18/dat/leap/cmd to search path.
-s: Ignoring startup file: leaprc
-f: Source tleap1.in.

Welcome to LEaP!
Sourcing: ./tleap1.in

/mnt/d/amber/amber18/bin/teLeap: Fatal Error!
source: Improper number of arguments!
usage: source <filename>

my file has the following entries


source leaprc.protein.ff14SB
source leaprc.gaff2
source leaprc.water.tip3p
loadamberparams frcmod.ionsjc_tip3p
set default PBradii mbondi3
rec=loadpdb rec.pdb
loadamberparams bras.frcmod
lig=loadmol2 bras.mol2
gascomplex= combine {rec lig}
savepdb gascomplex bras.complex.pdb
saveamberparm gascomplex bras.gas.complex.prmtop bras.gas.complex.rst7
saveamberparm rec bras.gas.receptor.prmtop bras.gas.receptor.rst7


i used the command

tleap -f tleap1.in

Am i doing anything wrong?

Thank you for your guidance
