[gate-users] set the tumor/background activity ratio

[null99 at mails.tsinghua.edu.cn]

Dear Jin,

Yep, Gate mannule (GM) can't provide the right type information for you. The
attachment is a brief list of command appeared under:
/gate/source/your_source_name/gps/

Sorry, because my mouse's problem, I can't paste it for you.

Good luck!

Long Zhang
