Hi everyone, I am trying to extract waveforms (30 time windows) from the land.mseed package using rdseed. I put the station metadata with the -g option in the file called land.seed. However, I got a 'Volume Not Found' error, which I couldn't solve. I attach the terminal output.

Hi, I use sac v102.0 (64bit) on Kubuntu v16 (64bit) . After FFT of a squared waveform (amplitude unit is count), the maximum and minimum values on the header are FILE: 1-SAC/a.sac - 1 -------------------- DEPMAX = 1.441192e+13 DEPMIN = 7.639150e+07 NVHDR = 7 However, I give the following command message " max-min &1,DEPMAX &1,DEPMIN " max-min -2147483648 76391496 The maximum number is not true, so I cannot normalize the data. The value of the &1,DEPMAX is the limit of 32bit… [more]
