[ESPResSo-users] Getting particle position

[Paul Peterson]

Hi,

referring to this (quite old) thread:

https://lists.gnu.org/archive/html/espressomd-users/2010-06/msg00023.html

I try to get a particle position writing:

set ppos [part $pid print pos]

but I don't know how to address the coordinate values in the ppos variable.

When I print it out it looks correct (3 coordinate values are displayed) but when I try to address, for example, the x coordinate with ppos(1), Tcl complains that ppos is not an array. What should I do then?

Would be grateful for any suggestion,

Paul
