[OpendTect_Users] Scaling depth

[Friso Brouwer]

I agree with Mike, easiest is to reimport the data , choose "No the file is
not segy rev1" when prompted during the import, this will give you most
options to overrule any segy headers that need to be overruled.

Regarding Salva's suggestion I also wanted to mention that the current
development release (430d) has included a tool to manipulate segy headers
values (accessed via the segy import and export). Probably you will not
need that tool to import this 2D data correctly, but it is a will help you
to prepare incorrect segy files for other applications or add header values
that are not set in the regular OpendTect segy exports - e.g. adding an
offset or azimuth header to an seismic attribute volume generated from a
specific partial stack.

Cheers,

Friso
