When associating the data with network for EM parameter learning, click on the 'Fixed nodes' button (in the lower left part of the 'Match Network and Data' dialog). Select the nodes for which you want to keep the current parameters; in your case this will be root and leaf nodes.
Thank you for your ...

How to learn the parameters of middle nodes?
The structure of the BN has been established, and values of probabilities of root nodes (Xi) and each of the conditional probabilities of P(T|Xi) are acquired (T denotes the leaf node).
Are there any methods to learn the conditional probabilities of middle nodes (e.g. P(Bi|Xi), P(Ai|Bi), P(Ci|Xi), P ...
