In Develop mode, the program shows a Cell Types tab at the bottom of the main window. This is where you will find many of the tools for developing a model. This tab contains a set of tabs, one for each Cell Type that has been defined in the model. Each Cell Type tab has a Cell Type Widget that includes all of the Expression Profiles used for that Cell Type. The tab can also include other graphics and tables added by the user.
On the left side of the tab area, a collapsible section includes Cell Type Properties and Expression Profile Properties.
