Thanks for your reply!. After trying I find the loop in your example
should be:
for {set r 0} {r < $runs} {incr r} {
run $incr_step
callback foo
}
Actually I am trying to analyze the gaussian accelerated molecular
dynamics (GaMD) results in the foo proc. I need collect the delta V
every step, so should I reduce the stepspercycle to 1?
