Understanding the Framework option

Dear members,

I'm new to RASPA. I want to simulate ice-Ih configuration to compute enthalpy at a given T and P. Can I use Framework option to give the input configuration? I tried it, but the output showed that framework atoms-512 (which i gave) and adsorbate atoms (zero) and crashed after that.

Is the framework option is only for adsorption studies? Is there anyway I can give the .xyz coordinates of ice as an input configuration?

Thanks and regards,

David Dubbeldam

Structure-input is expected in cif-file format. In RASPA they are used to study adsorption and diffusion, but you could also develop a force field for your framework.
In case of water (or ice), these can be seen as "adsorbates" without a framework. For that, you need to generate a restart-file to start from these initial positions.
See the manual.
