Hi Gordon, Whether a URL resolves to a symbolic link or regular file on your server shouldn't matter to us. Can you access the new symlink'd URL using a regular web browser? If a regular web browser can access a URL (probably asking if you want to save the .bam file locally), then our servers should be able to access it. If you'd like, you can send me the URL that uses a symbolic link and I can help to diagnose.
