Yes, I mean I don’t know if the “output” command works from TclForces. He
need to try, otherwise he would have to set the restartfreq suitable for his
needs.

Dear Norman and Thomas,
It works also within tclforces. You must be ready to a slight loss of
performance for the additional I/O work. Anyway the following procedure has
been tested and have worked fine for me since version 2.8. Hope it will help
------------------------------------
proc readcell {xscfile} {
if {[catch {open "${xscfile}" r} xsc]} {
puts stderr "ERROR opening ${xscfile}
CHECK!!!"
exit 1
}
set in [read $xsc]
set bcell [list [lindex $in 28] [lindex $in 32] [lindex $in 36]]
print "readcell: read cell, at step [lindex $in 27] was $bcell"
close $xsc
return $bcell
}
-------------------------------------
simply usage:
set boxcell [readcell <xsc filename>]
Best regards
Salvatore M Cosseddu

Hi,
I was also searching for such a command, but the only way you are currently
able to do it, seems to be using the “output” command to write a set of
restarts and read the box info out of the xsc file. No idea if this is also
possible within TclForces, but its working from jobscript context. Also,
just to mention it, the only way currently to “set” the box during
simulation is by loading dcd frames with the “coorfile” command.

Dear NAMD community,
Is it possible to get the current unit cell vectors on the fly from within a
tcl forces script?
