 Dear All
 I am running an optimization job, followed by rigid PES scan.
 In the energy calculation, we are going to take BSSE into account.
 But what's about Scan? how can I add BSSE option into PES.
 Can I calculate the BSSE for the optimized structure and then added the
 calculated BSSE to all the scanned energies?
 I have also one more question, during the scan I found more stable
 configurations, but when I took the most stable configurations and optimized
 it, I found it is not stable and shifted to a weird configurations. BTW the the
 energy difference between the start optimized structure and the most stable
 configuration (got throughout the scan job) is around 2 kcal/mol. Any
 explanation for this shift?
 Any kind of help would be highly appreciated.
 Thanks Eliac
