4. Set the analysis name and metadata and then click Next.

   Information noteImportant:

   Do not use the following special characters in the item names: ~ ! ` # ^ * & \\ / ? : ; \ , . ( ) ¥ ' " « » < >

   These characters are all replaced with "\_" in the file system and you may end up creating duplicate items.
