<DIV> </DIV>
<DIV> </DIV>
<DIV>My problem is I can't read my file after saving it to the disk.</DIV>
<DIV>For example, the original file is the amplitude file in x,y file type. Then, performing the division operation by other file, and then FFT, will produce the spectral data file type. Which I have to save it on my disk as a file(in binary or ASCII).</DIV>
<DIV>The problem is, when, I save it using the command "WRITE SAC" it successfully saves my file, as binary, spectral file.</DIV>
<DIV>But, when, I use the command "WRITE SP", with no error. But, when I try to read this file it says "ERROR 1301: No data files read in.".???. Even, when I use the command "READSP" it gave me this message "ERROR 108: File does not exist:".</DIV>
<DIV> </DIV>
<DIV>I don't know what is going wrong with me..???</DIV>
<DIV> </DIV>
<DIV>Any Idea on what going on with my files, highly appreciated.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>My regards,</DIV>
<DIV>Talal</DIV>
