First I insert 4 images, the results reveal 02 image is the highest energy. I choose the 02 and 03 structures, then insert 4 images between them. After adding 4 more images between 02 and 03 the working directory will consists 00, 01, 02, 03, 04, 05, 06 where 00 and 06 are actually 02 and 03 from earlier calculation. Now, my question is what will be POSCAR in the 00 and 06 directory. Whether it will be the earlier POSCAR or the CONTCAR (of first NEB) should be copied to POSCAR?
