Outputting cell information and fractional coordinates

Hi FX,

I could provide a dumpdcd code for CP2K output files in DCD format. Atomic 
labels are added if a prototype XYZ file is provided. It has also some 
additional features like frame selection (first/last dumped frame, stride), 
an optional application of PBC boundary conditions and a dump of all 
out-of-box atoms. I use often the DCD format, because it allows the 
consideration of the cell information e.g. VMD. I would put the code into 
the cp2k/tools folder in case you are interested.
