Each loop type has a different set of metadata which must be assigned using .

The definition dialog is partially filled by default. The non-parsed columns could be edited. Clicking on inserts the default values.
Figure 1223. Position Loop definition
In the Define Position Loop dialog, the position of each point should be filled. Positions are supposed to be set in the “large image coordinate system”. For example when there is no overlap, the step in x-axis direction between the neighboring frames can be calculated as frame width * calibration (see the image below). Positions can also be imported from MS Excel clipboard using the 
Paste from Clipboard button in the toolbar of the definition dialog.

In the definition dialog for a well loop, a well-plate must be selected in order to be able to correctly parse the well position.

If all the needed information is filled, the status bar at the bottom of the main dialog shows the “Loops are correctly defined.” message and is enabled. Otherwise warning messages are shown.
