@julienchastang thanks for your reply. I don't believe I'm able to see the NCML files. I've put some screenshots together here in sequence:
http://imgur.com/a/4oI3q#01. Add the catalog.xml in the Data Choosers
2. Select Image Collection in the Field Selector and click Create Display
3. The error I recieve when I click create display: "Unknown XML root:catalog"
4. The subsequent Image Collection screen which I'm not sure how to use.
Thank you again for continuing to engage with me on this.
