I got positive results for total_score after symmetry docking. At the first time, I run the symmetry docking without native structure. the rmsd was not created in the score.fasc. I guessed maybe because I did not specify the native structure. So I use one of the reliable structure obtained from protein-protein docking as a native structure. After doing this, the rmsd is appeared in the score.fasc file. But I got the positive results for total_score. I do not know what the positive number means.
