Cannot Import segy. file

[yshigei]

Hello,

I am trying to import .sgy file extracted from Petrel (P-Impedance cube/Post Stack). segyio.open() successfully worked, but cannot read through inline/xline (segyfile.iline/xline/depth_slice... did not work).

How could I fix this issue??

It would be appreciated if you could help my problem.

Best Regards, yshig

Your file handle has been closed before you reach segyfile.xline[segyfile.xlines[1]] in your code. Do you perhaps use python's with-statement with segyio.open and then left the inner scope?

Thank you very much @ErlendHaa. After fixed my indent as your instruction, it successfully run.
