Lineage Classification on 2 datasets with a joint Dendrogram

[stefanhahmann]

User Story

As a user of Mastodon, I would like to use the existing "Classifify lineage trees" method on 2 (or even multiple) datasets. With this, I would like to see, how similar the development of two embryos is.

Implementation Idea

• Use a dialog similar to the lineage registration dialog, where two mastodon datasets can be selected
  • E.g. all dataset in a specifiable folder
• Allow the user to set prefixes from both datasets that are used to differentiate results
• Allow the user to set a time scale that can be applied to compensate for different timelapse frame interval or differing speed of development
• Compute a dendrogram on the joined dataset
• Assign the generated tagset to both datasets
