[CP2K:480] Re: Reading topology file

[Teodoro Laino]

Hi Chris,

a simple and additional comment to the one of Axel:
I'm sorry to say that just reporting an error without providing ALL  
the files in order to reproduce the error is most of the times useless.
There are several reasons why you may have hit into this problem,  
even a possible bug in the code.
Unfortunately if we don't work on the same files and cannot reproduce  
the same error we can't say too much. I highly suggest to all the  
people asking for help to provide ALL input files (i.e. input  + all  
the additional files necessary to run it).

cheers,
teo
