IMD
This is part of the imd module
It is only available if you configure PLUMED with ./configure –enable-modules=imd . Furthermore, this feature is still being developed so take care when using it and report any problems on the mailing list.

Use interactive molecular dynamics with VMD

Examples
# listen to port 1112 of localhost
IMD PORT=1112
# listen to port 1112 of pippo
IMD HOST=pippo PORT=1112
# listen to port 1112 of localhost and run only when connected
IMD PORT=1112 WAIT
Attention
The IMB object only works if the IMD routines have been downloaded and properly linked with PLUMED
