For a single rule network, if the file is for a different neighbourhood size k, the file will be accepted (in the main prompt sequence only, not when resetting rules at a later stage). The k setting of the network will be automatically altered with a top left message, for example,
rule loaded, nhood changed from 5 to 9, cont-ret: (values shown are examples)
Once loaded, the rule is displayed in the rule window.
For a network with a rule mix (or when resetting a single rule at a later stage), a file with a different k will not be accepted, with a top left message, for example,
not loaded, tried nhood 9, this nhood=3, cont-ret: (values shown are examples)
