 A: This means that the preprocessor crushed unexpectedly! Sorry for that! Report the problem in the forum and it will be fixed 
 soon.

-Optical processing (ELDA) failed but no Exit code is provided
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Q: The optical processing of one of my measurements failed (I get a status -127). However, when I check the Exit codes 
-to see the description of the problem, there is none. What does this mean?
-
-A: The reason for which ELDA failed it's not currently easy to find because 
-this module does not implement yet the setting of a specific error code for a 
-specific error. Based of past experience, when something like that happens is 
-due to a poor S/N ratio of the pre-processed signals. What you could try to do 
-to debug the problem is:
-
-* try to increase the S/N ratio of the pre-processed signals, for example by increasing 
-  the pre-processing vertical resolution or/and the pre-processing integration time.
-
-* look at the pre-processed signals produced for this measurement and see if 
-  there is something wrong in them.
