I have been unable to upload data files into Galaxy Main since Friday 18th May 2012. Today is my fourth day of attempting uploads. Refreshing and leaving the files to upload overnight does not work. Although Jennifer has stated the bug has been fixed at 5.30pm today I am still unable to upload data files. I thought I may be exceeding maximum file capacity but I am well below at only 1.8Gb.

Hello Megan, Are you still experiencing problems now? Galaxy may have been busy immediately following the resolution of the cluster problem, although your problem does appear to be unrelated. It sounds like you are uploading file through a browser. A better choice would be to use FTP. This is required for datasets approaching or exceeding 2G in size. Files that are < 2G, really any file over ~ 500MB, can also benefit from FTP upload. An FTP client tracks the progress of an upload and can resume an interrupted transfer. http://wiki.g2.bx.psu.edu/FTPUpload Hopefully this helps, Jen Galaxy team -- Jennifer Jackson http://galaxyproject.org

Hi Megan, I ran a few tests and found that changing the file suffix to .txt when using the "autodetect" upload type function speed up the loading process considerably. As the final result is an identical Galaxy dataset to what is produced with using the existing suffix, this is something I would recommend that you try next time. For my test, I took one of your files and change the suffix directly, no other changes were made to the content, as it was already a tab-delimited text file. I didn't continue with the testing to specify the datatype at upload (tabular would be the correct choice), but this is a change that may also speed up import slightly, although the .txt suffix change was dramatic alone and the upload was quick (I ran a side-by-side comparison of an original and .txt-suffix modified file). The general reason behind this is that Galaxy will interpret data to detect and confirm datatypes during upload to create associated metadata needed for tool use. Detection is a convenience option that comes at a cost (compute resource and time). If you can provide this information instead, the detection portion of the process can be avoided, confirmation and metadata creation can be started directly, and the result is a quicker upload. Hopefully this helps for next time, Jen Galaxy team -- Jennifer Jackson http://galaxyproject.org

Hi Megan, If some columns of data were empty, then there should be two adjacent tabs in your data, and Galaxy would leave a blank, empty value in that column. You will need to check how your application actually output the data, possibly pad the empty values, and consider to exporting directly as plain, unformulated text if at all possible. You could also try padding these empty values with a null value. Commonly used values are a dot "." and a zero "0". Different tools will expect different null values, see the tool forms for expected input formats. Completely blank values will cause problems with many tools. Probably also would want to avoid " Convert spaces to tabs:", unless you know this will produce the correct output. Best, Jen Galaxy team -- Jennifer Jackson http://galaxyproject.org
