Please send an email to software.support@ecmwf.int or go to Issues if you have any suggestions for improvements or have discovered a bug with any ECMWF software package.

When you enter a new bug please supply the following information:

• Product and Version
  In which product/version did you find the bug? E.g. using GRIB_API version 1.9.9
  
  
• Platform (OS and architecture)
  Please select the platform and the OS version that your bug occurred on. (This could be the output from "uname -a") e.g. "OpenSUSE 11.3 (64bit) ..."
  
  
• Short summary
  How would you describe the bug using around 10 words? A good summary should quickly and uniquely identify a bug. Explain the problem, not your suggested solution!
  
  
• Detailed description

  Actual Results: What happened when you got the bug?

  Expected Results: What was supposed to happen?

  Additional Information: Add anything else you feel the developer needs to know e.g. The exact error message printed
  
  

• Steps to reproduce:
  

  This is the most important part of the bug report! Ask yourself “How can a developer reproduce this bug on their own computer?”

  First reproduce the bug yourself several times. If it is not reproducible every time you can still enter a bug mentioning the intermittent nature of the bug.

  Attach any accompanying data
  
  

Note: The higher the quality of the bug report, the higher the chance that it will get fixed!

Thank you
