Hi Amanda, Thanks for the report. Maybe add some print() or type() statements to try to get to the bottom of it? I will take a look as well.

Good afternoon,
I am trying to save synthetics from MTUQ to visualize against real data. I have done this with SPECFEM-generated Green's functions, but when I attempt to do the same thing using an FK database, no synthetics are generated. I cannot share the FK database of course, but these are the basic commands of what I am doing:
fk_path = '/store/wf/FK_synthetics/'+model db = open_db(fk_path,format='FK')
origin = Origin({ 'time': '2022-09-24T15:18:54.694000Z', 'latitude': 61.4915, 'longitude': -145.5887, 'depth_in_m': 41000.0, 'id': str(eid) })
data = read(path_data, format='sac', event_id=event_id, station_id_list=station_id_list, tags=['units:m', 'type:velocity'])
data.sort_by_azimuth() stations = data.get_stations()
greens = db.get_greens_tensors(stations, origin)
synthetics = greens.get_synthetics(MomentTensor([269000000000000,-15643000000000000,15374000000000000,5999000000000000,7576000000000000,4205000000000000]),components=['Z','R','T'])
os.makedirs(eid+'_synthetics',exist_ok=True) synthetics.write(eid+'_synthetics/%s/' % model,format='sac')
As I said, this works when I am using SPECFEM-generated GFs, and the only thing that changes is how I open the GF database:
SF_path = './GFs/%s/%s' % (eid,model) db = open_db(SF_path,format='SPECFEM3D')
Is there something that needs to change about my approach to get synthetics from an FK database?
Thanks, Amanda

It looks like the network, station, and location codes are not getting copied to the synthetics. The result is the following output file names.
...R.sac
...T.sac
...Z.sac
One way to get the correct filenames is to manually pass a list of ObsPy stats objects via the stats
keyword argument when calling get_synthetics()
.
The syntax would be something like
synthetics = greens.get_synthetics(mt, stats=stations, components=components, mode='map')
This gets complicated though, I would have to look closely in order to recall the exact correct syntax.
Of course, we want these station codes to get passed seamlessly... trying to figure out a larger fix
