[OpendTect_Users] Interpreting reflector with a phase shift

[Michael Heeremans]

 Hi,

 If you say 'instantaneous energy', do you mean the basic 'energy' 
 attribute?

 Could you also use the 'Instantaneous Amplitude', or is this what you 
 mean with 'Instantaneous Energy'?

 I've tried to interpret a horizon with an attribute as input for the 
 event to map. When I then display this attribute and try to interpret an 
 horizon, I get the message:

 **
 Saved setup has different attribute
 Either change setup attribute or change display attribute you want to 
 track on.
 **

 But in my case, these are the same.

 How to solve this?

 Michel
