[ESPResSo] NPT parameter problem

[Xinghua Shi]

Hi folks,

In the input file ~package/mbtools/scripts/main.tcl, the parameter for
NPT is something like

    integrate set npt_isotropic $p_ext $piston_mass 1 1 0

Just curious about the extra parameters "1 1 0", which not exist in
the manual, so couldn't understand the meaning. Is it used to adjust
the box size?

Best regards

Xinghua
