Hello everyone,
when I compile vasp.6.3.0 with vtst-197 and set " ICHAIN = 1 " in INCAR file, the output of OUTCAR are following :


VTST: version 4.1, (05/19/21)

CHAIN: initializing optimizer

OPT: Using VASP Quick-Min optimizer
CHAIN: Read ICHAIN 1

POSCAR: Si
positions in direct lattice
No initial velocities read in
CHAIN: Running the Dynamical Matrix

| Please check whether the tags are spelled correctly, have the |

I did not receive any errors during the compilation process, but why does the program not recognize the ICHAIN parameter? The attachment is a complete OUTCAR file.

However, when I use vasp.6.1.0 with vtst-197, I do not have this error.

thank you in advance.
