##Cytoscape 3 Data Import UX


### Scinario 1: Multiple Species Session
=====================


#### User Data
* n mouse network files
* m human network files
* 1 expression data for mouse
* 1 expression data for human


####Steps
1. File > Import > Network > File
2. Select a mouse network file and load
3. It creates a new (root) network
4. Load a second mouse network file
5. User will be asked to choose from the following options
    a. Add network existing network collection
    b. Create a new network collection
6. User should choose __a__ to add it to mouse network group
7. Reoeat 4-6 for n-2 times to create a mouse network collection sharing same root
8. Repeat the above for n networks for human
9. At this point, user have two network collections (root networks), one is for mouse, and the other one is for human.
10. File > Import > Table > File
11. Select the mouse expression data file and press OK
12. User will be asked the following:
    a. Map to selected network collection(s) - This means map to all networks under the selected roots
    b. Map to all networks
    c. Map to selected networks - User picks individual networks.  Networks can exist in multiple roots
13. User selects __a__ and pick mouse network collection (mouse root network)
14. Expression data sets are mapped to all mouse networks.
15. Repeat 10-14 for human expression data file


### Questions
* For step 12, if we have option b and c, can we cover a?  User have to select all mouse networks manually, but still it gives the same result.
