Hi! I am using the vtstcode-180 with vasp6.2.0. After I compile it, i do a structure relaxation job (it does not relate with vtst). Then vasp give some error massage such as
forrtl: severe (174): SIGSEGV, segmentation fault occurred

vasp_std 0000000001CF744D Unknown Unknown Unknown

The relaxation job failed after the first ionic step.

If I do not install vtst, the job can finish normally. So I think there is something wrong with vtst. Does vtst support vasp6.2.0?

You have to make one additional small change in main.F. On line 889, change:

IF (LCHAIN) CALL chain_init( T_INFO, IO)

to

CALL chain_init( T_INFO, IO)

I should have added that to the installation instructions - I'll do that now.

Thank you for your reply!
