when I download my files (mzXML) from my external hard drive on galaxy, my files export, but on the right side (history) the files are in wait (they are grey).
I have already made matrices with the same files and everything worked fine.
The size of each file is 70 Mb and I have 34 files to import.
Can you help me?
If you would like to share a screenshot that would be helpful. Try to capture as much of your browser window with the Galaxy application shown (not just the history panel). Expand the datasets that are grey please so we can see the metadata.
And, where are you using Galaxy? Is this at a public Galaxy server? Which one? The URL at the top of your browser window is the best way to identify the server. If you capture this in the screenshot above that is good enough, or you can copy/paste it out back in your reply.
