Hi Andrew,

I don't know where did you get the ftp url. That's for internal use and outside users have no privilege to access the directory. If you could, please delete the url you posted in your post.

Please go to the webpage below to download the data you need. 

http://fcon_1000.projects.nitrc.org/indi...

You will be required to register and login before downloading. and the register link is on the webpage I gave here.

Cheers,

Yang
