Normalization of .hic files

I have two unbalanced .hic files generated by Juicer. I used chess-sim with the following command:

```
chess sim --background-query -p 24 /az_new/az_new.hic@2000@KR \
    /NPB_new/NPB_new.hic@2000@KR \
    az_npb_SBs.bedpe az_npb_syntenic_2kb.tsv
```

Dies the @KR work in this code? Would it compare the normalized matrices as a result?
