Negative rho values

Hi-

Thanks for developing this tool! I have 2 questions on running ERC.

1. If my master tree is quite different with gene trees. Can I use -g to fix the gene tree's topology before running ERC?
2. I used -g fix the topology and then run ERC. I got some negative rho values, is it reasonable? I run for mt and nuclear OXPHOS genes so I assumed that the values should be mostly positive.
