According to the documentation, the DPD pair style scales sigma to temperature, so we don’t need to change the drag parameter with temperature. Does it do the same with the self interaction parameter given that it requires a similar scaling with temperature (at least it does for the parameter selection methods I’ve seen)?
I don't know what the self-interaction param is. I would
look in the code to be sure: src/pair_dpd.cpp. If there
is something incomplete or unclear about the doc
page, let us know, and we can amend it.

Jacob,
You could use any conservative potential or parameters that make sense for your particular system, but sigma=sqrt(2 Kb T gamma) is hard-coded since its common to want a canonical ensemble.
