ERROR: Illegal read_data command (../read_data.cpp:297)

Dear all,

Kindly find the below attached molecule files and lammps script for my simulation. I am facing an error saying:
“ERROR: Illegal read_data command (…/read_data.cpp:297)
Last command: read_data cpme.txt add append toff 16 boff 16 aoff 31 ioff 10”

Please help me with same.

Thanking you in advance,

Gotcha. I was making a stupid syntax error.

There should “offset …” rather than " toff… boff… aoff…" in above input script.
