Has anybody tried getting SAC going on Mac OS X 10.12 Sierra? I can’t get the X11R6 directory over to /usr which used to do the trick. Apple has blocked the ability to make any changes to /usr Thanks, Steve Taylor

Hi Robert, I have given it a try using the rdseed executable you just send me without success. To confirm whether its rdseed or the data which has a problem, I tried two data sets (recent data-2016 and old data-1990).

INFO: sac variable EVDP will be in KILOMETERS WARNING (process_data): station/channel AF01/BHZ not found in station/channel tables for location: . Skipping this trace. WARNING (proce... [more]
