 Also, if you just have the behavioral XML and preprocessed ET data, you can run the function **ET_plot** instead.  This will look at all images and ignore any ROIs, otherwise and ROI must be present for the image to get plotted. Also, if you just have the behavioral XML and preprocessed ET data, you can run the function **ET_plot** instead.  This will look at all images and ignore any ROIs, otherwise and ROI must be present for the image to get plotted.

 +===== PupilOmetry in Matlab =====
 +
 +A matlab script based on pupilometry steps from {{:biac:analysis:2006_urry_neuro.pdf|Urry et al}} can be run to denoise pupil dilation data found in the preprocessed viewpoint WKS or cigal eyetracking files.
 +
 +The result will be a pupilchange element added to your behavioral+ROI XML.
 +
 +This example node has all previous steps run, pupil gotten smaller by 2.9% :
