Discovery of rare rules using SAS Enterprise Miner

Hi,

I am working with a healthcare data set and trying to discover associations between items (diseases) using the Association node in SAS Enterprise Miner. However the node settings has some limitations which do not let me to extract rare associations. The main limitation is the maximum number of rules it returns (limited to 10,000 rules). My data set involves a large number of diseases and the top 10,000 rules can only cover associations between a limited number of very common diseases. So I was wondering if there is any way I can request SAS to return a higher number of rules?

Thanks

Would it make sense to pull out some of the diseases, especially the super common ones or high frequency ones that you're not interested in?

There's also an association rules macro that you can find online that may not have the same limitation but it runs in Base SAS. You could use a code node to run it as well.
