+# Pixelator
+
+Pixelator typically adds thumbnails to HDF5 data files after a scan has finished. This is implemented in the `insertXMP.py` script that is called from the `endOfScan` script. This is not enabled by default but is easy to set up.
+1. Copy `~/pixelator/work/stxm/PixelatorController/config/PolLux/scripts/insertXMP.py` to your `config/scripts` directory
+2. Edit your `endOfScan` script to include a call to the `insertXMP.py` script, e.g." 
+```
+filename=$2
+python3 ../../PixelatorController/config/PolLux/scripts/insertXMP.py $filename
+```
+3. Edit your `settings.json` file (that is given as an argument to the Pixelator binary call) to ensure that the `endOfScanScript` parameter points to the script file above.
