Problem with seed list

[Thang Chi Duong]

Hello,

I try using LDSpider with the following seeds:

http://data.open.ac.uk/page/course/mu120

http://data.open.ac.uk/podcast/c36b583c57fb108d6879ee8f04ca8c51

and the following command:

java -jar ldspider-1.1e.jar -b 1 -s seedlist.txt -o output.nq  -a access.log

However, the output.nq and access.log files are empty. On the output of the command line, there is this warning: INFO: access denied per robots.txt for http://data.open.ac.uk/page/course/mu120. 

I wonder what is the problem here ? And how can I fix it ?

Thank you.

Best,

Thang
