Hi,

This looks like a problem trying to reach our FTP servers, possibly a network issue at your site.  Some IT departments block FTP at the wirewall for security reasons; we're hoping to move away from FTP in a future release for that reason.

For now, you can work around it by downloading the MSigDB GMTs and/or CHIP annotation files directly from our website.  Just supply the files through the Load Data screen along with your dataset files.

That will allow you to run independent of the FTP servers.  The disadvantage is that you won't automatically see any updates, so check back to our website or Twitter feed for new announcements.

Regards,

David
