Dear all,

Now, I'm currently trying to calculate minimum energy path for reaction.

I'm just using MEP calculation with "Full path" option, which consists NEB calculation and path optimization.

After NEB calculation, I got a NEB path with success of convergence.

But, afterwards, the path optimization only generates path from TS to product with the message:

***********************************************************************
* WARNING: Could not reach reactant from product with connected path! *
* Inspect results and restart with more connection steps or focussing *
* on specific reaction steps if required. *
***********************************************************************

How can I obtain the optimized path from reactant to product with accurate TS structure?
