  1. '''Remove background'''[[BR]]Browse for the right experiment again and chose the extracted ''.png'' images. The action ''sub_background'' that will remove all the motionless structures.  For the input you have to make sure that the ''image rescaling coefficient'' is equal to 2 and then make is run. (This process takes a long time, don't forget to make it run on the cluster). You can check on ''Status'', how many images are done. The output of this action is a file PCOY.png.sback filed with png images.[[BR]]For''' SCANS: '''Here, the ''image rescaling coefficient'' should be equal to 0! Also, set the ''Number of images for sliding background'' to the number of images per slice!
  1. '''Do PIV[[BR]]'''Browse for the images with the removed background''' '''(PCOY.png.sback.). Choose the Action ''civ_series''. For in Input, you have to import an existing .xml file to get the right parameters. You can use one .xml file from another experiment on which the piv is already done. Browse for: EXPXX/PCOY.png.sback.civ/0_XML and choose any of the img_#.xml. Make sure in the Input parameters that you chose the correct mask (right camera and with/without corner).
- 1. '''Add calibration grid[[BR]]'''To get all images in cm relative to our coordinate system, the calibration we did in the beginning has to be applied on all experiments. This can be done in the very end.
+ 1. '''Add calibration grid[[BR]]'''To get all images in cm relative to our coordinate system, the calibration we did in the beginning has to be applied on all experiments. This can be done in the very end.[[BR]]Chose any experiment and any image in ''uvmat'' and chose ''Tools>geometry_calib>replicate''. Click on NO, when ask if to apply on cropped images.Click okay on points that are off, if not too far off and click off for the assumed slice height. In the browser, chose a random file and select. In the window "''browse_data''", chose the data you want to apply the calibration on in the left column and chose the right Data Series on the right column (e.g. PCO1 for PCO1). The calibration will now be attached to all .xml files with the timing.
+ 1. '''Set slices[[BR]]'''To merge the two cameras, the slices first have to be brought to the right height. You do that by chosing any image from the right experiment. Chose ''Tools>Set_slices ''chose the height at which the laser sheet was, or the height of the first and last laser sheet and indicate the number of slices. Also important to check off refraction and type the water level. Refraction index should stay the default 1.33. For the ice shelf experiments, you can indicate the tilt of the laser layer by typing the 1.15% tilt angle y axis. The slice height can be replicated in the same way as the calibration data
