Hello, Maybe this was explained before but I cannot find an answer. After converting a 1200 sec SAC file, I am getting the ASCII file with 1191 data points. Why don't I have all the 1200 points? Here are some commands (the header values take 4 lines in my example) > cat CIFLS__L1Z__.sac.txt | head 1200 2016,336 07:55:00.000 1.0 1050,1240,1390,1115,840,1065,1290,1320,1085,850,1130, 1410,1530,1625,1720,1480,1240,1445,1650,1210,1020, 830,985,1140,1490,1240,990,1125,1260,1370,1205, 1040,1250,1… [more]

Hi, I've noticed that when I do a SORT (e.g. SORT GCARC), headers STLA and STLO vanishes from the memory. I am using SAC 101.6 on openSUSE (Bottle). I was able to reproduce the same error on Mac OS X (Mountain Lion). I wonder if others can reproduce this issue and if it is a bug? Thanks !
