The use-case for region importing is precise definition, for example, when creating regular region grids in plant phenotyping or using external labeling and annotation sources.


In order to import region definition from an Excel file, use Data / Regions / Import regions menu command:



Extending our export regions example, we now add an extra note to the "reg2" region in Excel and save the file.



  • In order to import regions, we need to first remove the existing regions using Data / Regions / Remove all regions command (when specific scan or scans to be affected are selected in the Images list). Note that this follows the general perClass Mira design principle of not destructing any information behind user's back.
  • After removing the regions, we can use the Data / Regions / Import regions command and point to the updated Excel file.


The new region definition now contains the text note for the region "reg2" as well. In this same way, we may create entirely new regions or change positions and class assignments of existing ones.
