Result analysis

Can I open a table in ImageJ instead of JIPipe or vice versa?

Yes, and even more: Depending on the data type there are multiple options on displaying data available. Select the data in the result view or cache browser and click the ... button at the bottom. JIPipe will even remember the last setting for you.

Can I save data by their metadata?

Yes, use the node Miscellaneous > Export data. It will export all incoming data into one or multiple folders and generates names based on metadata.
