Not the entire tree - I just selected a few rows. On the first tree, the only status codes I saw were -1 and -3, which makes sense. I am guessing the final tree should never have a status of -2, which looks like an intermediate status, unless I am missing something. Thanks for the response.

If so there's a problem. The node status is defined as follows in rf.h of the source code: #define NODE_TERMINAL -1 #define NODE_TOSPLIT -2 #define NODE_INTERIOR -3 i.e., "-3" means "non-terminal" node.
