How To get MODECAR?

[edenantish]

I'm a new user of this site. Pls how coluld I generate MODECAR from a given POSCAR.
I used modemake.pl but it needs two files, POSCAR1 and POSCAR2. How could I generate these two poscar files?

THANKS

when I finished a CNEB calculations effectively, then I used the nebresult.pl applications, there was no problem. But the next stage, when I use the neb2dim.pl to generate the details for a new dimer calculations, the MODECAR is empty, why?
