[hts-users:03111] Re: Use reference tree for clustering


In the 2-stage clustering, tree are first constructed using the reference tree, then the standard clustering is performed. However, when using the reference information, the node is not split if any models are not assigned to a child node. After that, the clustering stops using the reference information.

Please check the question of root node of your reference tree.

I want to confirm if the new feature "Context-clustering can be started in
the middle of the tree building" of HTS-2.2 in HHEd could achieve the
2-stage clustering. For instance, load a clustered tree and continue to
split each nodes with new QS, then output the secondly clustered tree.

I tried the -q n (with 0~3) and LT command to load reference tree, use TB
command to do the new tree building.
However, the tree structure seems to reset while create the root of the
trees. It lose the structure of reference tree information I want to keep.

Does anyone know if HHEd in HTS-2.2 could do the work, or I use it in the
wrong way?

Thanks a lot
