Thank you very much for the response Mark!

I've looked at his .top and it seems to me that how he included it is by
adding "#include spc.itp". I've added that line to cyclohexane.top before
and after the "#include "cyclohexane.itp" with no success (same error as

I also saw that he added a force field. Would I need to do this if I am not
interested in a protein?

I want to avoid using PRODRG because it is online which admins can easy see
what I uploaded. I feel much more comfortable using programs on my system
(the reason I am using acpype).

Thanks again :)
