[AMBER] Antechamber + SQM/DFTB

 I am a new user of antechamber. I have read many manuals and examples
 to parametrize organic molecules with antechamber. I have installed
 AmberTools 12, because antechamber is distributed with it.
 In the beggining I don't have any problem to create files and to run
 sqm, actually I asked for the DFTB Slater-Koster files to run sqm at
 DFTB level, I have not been able to find an antechamber flag to calculate the
 atom charges using that method. So, I generate sqm.in with
antechamber and manually I
 must change AM1 to DFTB in 'qm_theory=' flag. In fact, the calculation
 finish well. However, I don't know how to use antechamber or any
 command to generate a mol2 or frcmod file using that calculation

Does exist any command to say directly to sqm calculate in DFTB level?
 What can I do to obtain coordinates and changes from sqm.out file?

 Thanks in advance
