How to select docked models

Dear all, 

I have generated 500 docked complex model with docking_protocol.linuxgccrelease using a command like this:

docking_protocol.linuxgccrelease

  -s start_prepacked.pdb

  -partners A_B

  -dock_pert 3 8

  -ensemble1 prot1_ensemble.list

  -ensemble2 prot2_ensemble.list

  -out:path:all docking

  -nstruct 500 | tee docking.log

I wish to select 10 out of the 500 models for next step such as local refining. However, I am confused about the selection criteria. Accroding to the docking protocol available on net (https://www.rosettacommons.org/docs/latest/application_documentation/docking/docking-protocol), two scores can be referred to: the “total” (column 2) and “I_sc” (column 6). And the “I_sc” should be more relevent. So I run this command:

    sort -n -k6 -k2 score.sc | awk ‘NR<=10{print $2, $6, $40}’

and get: 

  total         I_sc              model  

  -512.410    -19.416    start_prepacked_0314

   935.903    -17.147    start_prepacked_0176

   368.028    -16.874    start_prepacked_0490

  -469.329    -16.648    start_prepacked_0256

  -712.922    -16.225    start_prepacked_0013

  -312.844    -15.919    start_prepacked_0263

  -453.569    -15.693    start_prepacked_0389

  500.628     -15.370    start_prepacked_0096

  -626.392    -15.345    start_prepacked_0068

  -641.953    -15.313    start_prepacked_0280

If only considering the I_sc, it seems that I should pick up these 10 models, but some models in these list, such as the second and the third models, have very high positive total_scores. Should I just rule them out or keep them for local refining? Would local refinement lower the total score? 

With many thanks
