Hi nagesh,

either you find on the web some good guy that provided a script to 
convert DL_POLY  FIELD file into  .psf and .pot or you do it yourself: I 
had a quick look at the FIELD structure and it's just a matter of 
re-organizing the information present.
At the moment, given the limited request, there is no intention from my 
side to support FIELD files: of course contributors are more than 
welcome (i.e. if you want to implement it in CP2K I will be happy to 
support you).
