Re: No relaxation during CI-NEB calculation
It doesn't seem like you have our vtstcode linked into your vasp binary.

Re: VASP-MD velocities and VACF
I will need some more guidance about the actual problem here. Everything should be molar mass, and I believe that it is.

Re: den2vasp.f90 does not work for 48 atom unit cell crystal
You will have to contact the authors of the den2vasp code for help with this; we do not use castep and do not have the expertise to help debug this.

Re: Bader Installation problem
I'm sorry to suggest trivial things, but check if is the bader binary is there, and maybe run ./bader in case . is not in your path.

Re: Error compiling vtstcode 6.4 for VASP 6.4.1
did you edit the .objects file as described here: https://theory.cm.utexas.edu/vtsttools/ ... ation.html ;
you can follow the directions for vasp 6.3. We'll make an update for 6.4, but it is the same - just get the files from the vtstcode.6.4 directory.

Re: GSSNEB
This looks like a very nice path to me. If you want to improve your estimate of the minima and the 2 lower-energy saddles, then you can break up the path. But if you just want to know the three steps along the path and the overall barrier - it looks like you have that converged nicely.

Re: Prefactor convergence
Ok, do check not only convergence but that each displacement has converged to the same electronic structure (spin state and charge occupancy on the O and metal centers). It just takes one structure converging to a metastable (electronic) state to mess it all up. Also look at the frequencies and see ...

Re: Prefactor convergence
I think that there is definitely something wrong with the high prefactors in the high U_ox calculations. But first, do you really want to add +U on oxygen? This is intended to correct for delocalization in d-states of metals, not p-elements. Anyway, what I can say is that adding +U make the converge...

Re: NEB/ neb.dat (wrong energies)
I don't know this error, but I can see that it is inside the electronic structure optimization. Also, while it does report this as an error, it seems to have continued the calculation, so you might be ok. If it continues to cause trouble, I would suggest trying a different IALGO optimizer, and/or ch...

Re: Total number of electrons different in Bader and in DFT
I'm assuming the charge density that you have is the total charge. See if you can get the valence charge as well. Then you can do the analysis on the total charge but integrate the valence. The valence charge should be smoother and will likely sum properly.
