	In order to generate seismograms, jbsim3d must be run twice. The first time, in addition to the arguments above, also provide extract_sgt=1, extract_sgt_xfile=<extracted_x_sgtfile>, and extract_sgt_yfile=<extracted_y_sgtfile>, and leave out seis_file. What this is doing is taking the large SGT file, which has SGTs for the whole volume, and pulling out only the SGTs needed for this particular earthquake. Once this is done, run jbsim3d again, with extract_sgt=0. Also, point sgt_xfile to <extracted_x_sgtfile>, and sgt_yfile to <extracted_y_sgtfile>.

−	For now, I would strongly suggest we not worry about synthesizing seismograms. In order to use jbsim3d to synthesize seismograms from AWP SGTs, the separate header files must be created. CyberShake has codes to do this, but right now they take as input certain files which are produced as part of CyberShake which the tomography workflow doesn't have. Some code development will be required to bridge this gap in the tomography workflow.	+	For now, I would strongly suggest we not worry about synthesizing seismograms from AWP SGTs.

 A source is also needed for SGT calculations.  For CyberShake, we have pre-created impulses for various DTs and the X and Y components - if you look in AWP-ODC-SGT/utils/data, you will see sample sources for 20000 and 40000 timesteps (fx_src_20000, fx_src_40000, etc.)  These are simple pulses.

 Compile Getpar first:
 # cd into Getpar/getpar/src.
 # Edit Makefile; comment out line 56 ("../../../Compilers.mk") and edit the next 2 lines to that CC and FC point to the names of the C and Fortran compilers in your environment.  On many environments it's gcc and gfortran; on Blue Waters it's cc and ftn; on Mira I think it's bgxlc and bgxlf, but I could be wrong.

-Once that's done, compile JBSim3d_header. cd into JBSim3d_header/src directory.  Load the GNU compilers into your environment, and change CC and FC in makefile to the names of the C and Fortran compilers in your environment, like you did with Getpar.  Then run make.  It will produce the executable jbsim3d.
