I am having difficulty with data that I uploaded to galaxy via ftp server. I was successfully able to upload it to galaxy. After logging out and then back in, the data was gone (0gb though the "using" bar shows up as 13%)...Is this a glitch that has happened before?
Does it disappear from the FTP folder or from a history you imported it into? FTP folders are systematically cleaned and data will get deleted after 14 days I think. The imported datasets should never disappear from your history though, unless you choose to.
