[OpendTect_Users] 2D interpretation

[Eric Bouanga]

Dear Kamala,

We were unable to reproduce the problems you encountered while tracking 
long 2D line.
Five 2D horizons were interpreted using 470 km long 2D line (25 m 
spacing), tracking on both windows and linux platforms, using our latest 
OpendTect version (V 4.0.1f).

To have solve problem, we would like to have more information for example:

- OpendTect version used and platform (screenshots if possible)
- It might be helpful to send me the horizon file (extension .2dh) 
itself, this can be found in Surfaces subdirectory of your survey.
However, it must have been saved in ascii-format (not in binary) to 
enable us to look for anything peculiar.
To assure this, go to menu Utilities->Settings->Advanced..> Personal 
settings > Select "Surface.Binary format" as the settings keyword, and 
"No" as the value. After that, (re)save the horizon.

Best regards,

Eric
