Re: ZPE corrected Energy barrier calculations
I think that you are right. That ZPE script just calculates quantum harmonic corrections to TST, so zero or negative modes will lead to a divergence. If you can identify 3 translational modes at both the reactant and saddle, as well as (perhaps) 3 rotational modes, you can simply remove them and run...

Re: What vtstcode whould work with vasp6.2.1?
Don't use vtstcode6.4; use vtstcode6.1 (it is in our vtsttools download). That should work for vasp6.2, but if there are problems, I can send a specific version that will work.
Also, yes, here is v182:

Re: What vtstcode whould work with vasp6.2.1?
Ah no use the code in vtstcode6.1. If you have any problems, please let me know. We have changed the vtstcode version system so that it just matches the version of vasp.
But also, maybe just download vasp6.4 so that you have the latest version.

Re: CI-NEB
You can select degrees of freedom near the atoms that have moved in the reaction and look for convergence as you add more degrees of freedom. We have some scripts for this, such as dymseldisp.pl. Note that you can also combine dynamical matrix calculations with our code, and run any/all displacement...

Re: Bader Installation Problem
It is not building the binary because it can't find the associated libraries at the linking stage. Try removing the -static from the makefile; the static libraries might not be installed.

Re: How to integrate CHGCAR values in Z-direction of a cell?
It seems that we don't have a script for exactly this task. That said, it would be quite easy to modify one of our chg* scripts, which will allow you to read chgcar files, and then integrate over which ever dimensions that you want.

Re: Error Compiling VTSTCODE for VASP 6.3.2 (No rule to make target `bfgs.f90', needed by `bfgs.o')
Make sure that you have copied the source code from your vtstcode/vtstcode6.3 directory into your vasp.6.3.2/src directory. Also do a "make clean". If these steps don't work, please let me know.

Re: Movies in .xyz format
It looks like we have turned off writing of .xyz movies by default. There is a flag at the top of the script that can turn that back on. If I remember correctly, the issue is that the cell structure is written in POSCAR files but not (nessecarily) xyz files.

Re: NEB convergence problem
The biggest problem is that you don't have our vtstcode linked into your vasp binary. You have appropriate settings for the VTST code, but as it is, you are telling vasp to do nothing (IBRION=3, POTIM=0), so there has been no relaxation from your initial path.

Re: While linking VTST with Vasp got Syntax error, found IDENTIFIER 'TSIF'
I'm guessing here, but you might need the TSIF ... on the next line as in: CALL CHAIN_FORCE(T_INFO%NIONS,DYN%POSION,TOTEN,TIFOR, & TSIF,LATT_CUR%A,LATT_CUR%B,IO%IU6) rather than CALL CHAIN_FORCE(T_INFO%NIONS,DYN%POSION,TOTEN,TIFOR, & TSIF,LATT_CUR%A,LATT_CUR%B,IO%IU6) also make sure to do a ...

Re: Visualization of MODECAR?
I can't remember the form of the MODECAR, but it should be easy to see if it is direct or Cartesian. Basically, I am just saying that you have a minimum structure and a displaced structure in a dimer calculation, then you can see the difference between them, which is the direction of the MODECAR.

Re: Visualization of MODECAR?
I think that the easiest way to visualize the modecar is to make a 2-image movie - one image at the minimum and the other at the displaced configuration. Going between these images should give you a sense of what the displacement mode is.
