Up to you...
- You control molecular orientation using RBRA: This is a 1st good point.
- Then, you apply multi-orientation, this a second good point.
Then , you might read:

Thanks, for pointing this to our attention. We are working on this
problem to try to make R.E.D.-III "less rigid": It is not normal it
works in one order and not in the other one... I let you know if we
solve this problem. However, the answer to the problem your reported
is definitively R.E.D.-IV...

Mol_m1 this is a single molecule (molecule 1) fit
Mol_m2 this is a single molecule (molecule 2) fit
Mol_MM2 this is a multi-molecule fit: in your case, you get the
fragment you are interested in.

TEST = loadmol2 Mol2file-from-RED.mol2
APPLY THE TUTORIAL .
http://q4md-forcefieldtools.org/Tutorial/leap.php
savemol2 TEST New-Mol2file.mol2 0
(or savemol2 TEST New-Mol2file.mol2 1)
=> fragment coordinates more correct (for R.E.DD.B. for instance)
saveoff TEST Your-name.off
=> for AMBER simulation
