Dear vmd community,

I am trying to use the pbctools plugin to unwrap the coords in my test system (a box of waters). I execute this script at the command line:
package require pbctools
set outfile [open unwrap.dcd w]
mol load psf ../solvate.psf dcd h2o.dcd
puts $outfile [pbc unwrap -all]
The script terminates without any errors, but the file unwrap.dcd is empty. What is the correct usage of pbctools? I tried adding the -verbose option to "pbc unwrap", but this gives an error: "pbcunwrap: unknown option: -verbose".
