-Creating an average image can be done with [[xray_data:averagemanyedf|timelessMeanFileSeries]] which is part of the [[software:timelesstools|TIMEleSS tools]]. Creating the median can be done with ''median.py'' which comes with [[software:fabian|Fabian]]. You can also calculate median and average images with [[software:imagemath|ImageMath]] but we have not used it in a while. There is an issue with file formats.+Creating an average image can be done from within the [[software:timeless_viewer|TIMEleSS Viewer]] Graphical User Interface, inside the ''3D-XRD extra'' menu.
  
 The median image is less affected by outliers than the average and is probably a better representation of your background. For some purposes you might still need to use the average image. The median image is less affected by outliers than the average and is probably a better representation of your background.
