Query regarding VCNEB implementation in USPEX–VASP

[Paras Patel]

Hello everyone,

I am testing VCNEB (Variable Cell NEB) calculations in USPEX 25 (Linux) with VASP, using an argon system and following the VCNEB example provided in the USPEX documentation.

From the output files, however, I am unable to determine whether the VCNEB calculation has actually started, or if the run has reverted to a standard structure search. The logs do not clearly indicate image-based VCNEB optimization.

I have attached my INPUT.txt and the relevant output files (entire run directory as a zip) for reference.
Could someone please confirm whether my VCNEB settings are correct, or point out what I should check to verify that VCNEB is being initiated properly? or mention what I am doing wrong here?

Thank you very much for your help.

Best regards,
Paras Patel
