about neb sccripts

dear sir For neb scripts, there needs to be OUTCAR files for the initial and final states placed in the 00 and NI+1, respectively. I have finished the neb calculation, but there is not OUTCAR file in the 00 and NI+1. How to get the OUTCAE file? Can these OUTCAR files be used, that obtained by ...

thank you for your reply I have stopped the dimer calcualtion for i thought it was wrong. I will restart it and give the result as soon as possible. I have a question: When i have got a saddle point, how i can trace out the minimum energy path and find the initial and final minimum images? I cannot ...

how to get the initial configuration in dimer method?

I read your paper about the dimer method for finding saddle points on high dimensional potential surfaces using only first derivatives. I have built a cluster, would you like to tell me how to generate 1000 random configurations around the minimum.
thanks
