problems about CEThreader

I want to get the similarity score of two protein contact map.

Now, I have obtained protein contact map by ResPRE. According to the readme.txt in CEThreader, I know that I should use CEdecomposition to get .ce file for each protein first and use CEthreading to compare two .ce files to get final similarity score. But I have some questions:

Which option should I use in CEdecomposition ( template or query ) to get .ce file?
For template: how can I get .pdb and .mtx file?
For query: how can I get .meta and .mtx file?

Finally in CEthreading, what can I do to get .prf(query profile) file ?

Thank you!
