How can I manually assign labels to ROIs?

[insertsk8 (Lee)]

Hi,
As in the “multi-point” tool or the “cell counter” plugin, I want to manually categorize different particles. Is there any way I can assign labels (e.g. Type 1, Type 2, etc.) to particles while linking/assigning them to the ROI? What I want is a result table with all measurements and an additional column with the manual categorization.

Thank you!
Lee

Hello Lee -

@insertsk8

Is there any way I can assign labels (e.g. Type 1, Type 2, etc.) to particles while linking/assigning them to the ROI?

Thanks to @LThomas, yes there is.

See this thread / post of his:

Define a "class/category" property for ROI?

Just to let you know that the ROI group attribute is now available with the latest ImageJ version. The current group associated to new ROI can be defined by the Menu but also edited via Properties of the Roi Manager (as well as via scripting). Roi of a given group have the same colour. Also Measure will return the group value in a dedicated column (for group>0). [RoiGroup]

I think you will need to update to a recent daily build to get it:
Help > Update Imagej...

Thanks, mm
