Hi Bob,
Actually, having looked at it further, it appears that there has been
quite a high COM velocity during my simulation (which is being removed),
and some of the coordinates have gone over -999, so a couple of
lines read:
-207.0612654-164.0880036-682.2872437-521.2708399-275.5480435************
-521.3560550-275.9826974************-521.9206418-275.9782509************
for example this is a typical line from my output file:
check COM velocity, temp: 0.018330 0.51(Removed)
I haven't tried running it on sander 7, but i am thinking of trying to see
if i still get high COM velocities.
I think the solution would be to subtract a constant value from all the
coordinates.
A work mate has been running other simulations with almost identical input
parameters on a different protein on sander 7, but is not getting high COM
velocities.
If you would still like to have a look at my files, then i would be happy
to email them to you.
Thanks for your help,
Cheers,
James.
