Hi LL,
Unfortunately the block for this plugin does not exists.
And as you can see on the plugin web page, you are not the only one to request this feature :
http://icy.bioimageanalysis.org/plugin/ROI_Intensity_EvolutionI just submitted a script which allow to export ROI intensity over time, just type "intensity evolution" in the search bar and you should find the script.
You can use it to integrate in protocol in the meantime !
Best,
- Stephane
