Thread: size of the ASCII data in points

Hi,

Can you send more information about how convert sac to ascii,
perhaps send a file sac to try, use external program to convert?
all information will be useful.

Because if you do:
sac> funcgen
sac> lh
you can see the NTPS variable have 100 points
after use write alpha command
sac> w alpha aa.asc
and obtain aa.asc
if you look it have the same 100 points, formatted in 20 rows by 5 columns.

HTH,

Milton

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,
1040,1250,1460,970,1075,1180,1420,1660,1500,1425,

cat CIFLS__L1Z__.sac.txt | tr "," "\n" | sed '/^$/d' | head

1200

1050
1240
1390
1115

1065

cat CIFLS__L1Z__.sac.txt | tr "," "\n" | sed '/^$/d' | tail; echo "----------"

1345
1470
960
1335
1710
840
1000
1160
1420
1680
----------

cat CIFLS__L1Z__.sac.txt | tr "," "\n" | sed '/^$/d' | wc -l

1195

Thanks,
Igor
