[galaxy-user] URL file upload... and file upload renamed

1. How do I transfer files using the URL? As a test I wanted to transfer a file to my local installation of Galaxy so I put in the location of the file on my Linux box. file:///home/bmladmin/demo_data-old/file.nii.gz<file:///\\home\bmladmin\demo_data-old\file.nii.gz> into the "Get Data" URL box. But it seems to think that this is code that I've pasted rather than a link to the file. Will it only work if it is proceeded by http? 2. Also, when uploading a file using "Get Data" it seems the file is renamed to dataset_'id'.dat in ~/database/files/000/. Is it possible for the file to keep its name rather than being renamed? Neil
