I am trying to upload a tab-delimited file for LEfSe on Galaxy. However, all my attempts gets a "Failed: Upload Request Failed (0)" message. I tried doing it using the 'upload data' link on the right side of the Galaxy page, the "Get data" link on the left and the little button with arrow at the top. Each time, I get the popup window to select file from drive, then set the selection to tabular, and click "start". The progress bar goes up all the way, then I get the pick failed message and nothing show up in the history list.
Thank you for any help!
