Hi,
check your structure with:
ambpdb -p ../dock71.top < ../01_GenerateSnapshots/enz_pep_pH7_com.crd.1 >
check_Complex.pdb
Is the pdb-File correct? If this is not the case, look in your generate
snapshot input file: If your simulation was carried out in water, you must
set the box information to yes. NTOTAL, the number of all atoms (with
water end counterions).
You must create a topology file from your complex without water and
counterions.
good luck,
Heike
