Can CP2K fixed part of atoms when perform CI-NEB?

[elbu... at gmail.com]

Good morning J. Ye,

I've done a few NEB calculations with CP2K in my life and I've always fixed 
the atoms with the following options:

**********
  &CONSTRAINT
    &FIXED_ATOMS
      LIST=1...45
    &END FIXED_ATOMS
  &END CONSTRAINT
  &BAND
    ALIGN_FRAMES FALSE
    ROTATE_FRAMES FALSE
...
**********

For the systems I was interested, at least, this worked fine, I always like 
to do the aligning and build the intermediate images on my own. I've used 
the CP2K versions 2.6 up to 4.1, and I've never had any problems. I would 
guess this has always worked, but I am not sure. I hope it helps. 

All the best
Fabio Negreiros R.
