Hi.

Thanks for your reply.

Of course, I tried to follow these instructions.
The problem is that all parameters are to be listed in .par file.
I don't want to change it. I'd like to specify parameters in .sgm file.

I solved this problem.
So, .sgm file should be^
    4.600000
    5    4    6    0    0    0    1    1

Hi,

Have you ever tried to follow the instruction from this page?

http://nwchemgit.github.io/index.php/QMMM_Appendix#Preparing_QM.2FMM_calculations_from_scrat...

There, you could get some idea about how to create new segment for QMMM calculation.

Best,
