Hi Jennifer,

Thank you for your answer. Although using "curl" command might be a good solution to overcome the incomplete downloads issue, this solution might not be enough user-oriented (as I don't think our users are familiar with using the command line). Anyway, we have developed a tool which allows the user to select one file from his history and to copy it to another user-given location on our server. So using this tool allows us to download the files correctly.

Also, this issue happened while trying to download a file of size about 250Mb.. Is this considered a large file?

And finally an other question comes to mind: What about people downloading their result files not knowing that the download was incomplete?
If the user doesn't check if the number of lines in the downloaded file correspond to what is shown in Galaxy history, he won't be able to know that the download fails.

And this is why I was wondering if there was some way to prevent incomplete downloads (using the download button). Or if there was some way to be warned automatically when the download fails.

Once again, thanks for your help and for that incredible tool that is Galaxy.

Best regards,
Jean-François

Subject: Re: [galaxy-dev] Incomplete datasets when dowloaded from history

Hello Jean-François,

For larger files, or if complete downloads seem to be a problem, using curl at a command or Terminal prompt is a great option. The syntax is:

% curl -O '<copied-link-from-dataset-disc-icon>'

I used the 'mailing list' version of the Galaxy custom google searches to find this thread.

Links to all of the Galaxy custom searches are in the wiki in the side bar and other places, but also at the top of the Support page for quick access:

Hopefully this helps,

Hi folks,

Some of our local Galaxy instance users seem to be experiencing some strange behaviour lately. I searched the mailing-list archive but I didn't found anything related, so I'd be interested to know if somebody already had the same issue.

The problem is that sometimes, when people are trying to download their datasets from their history, although the file seems to download successfully, it appears that the downloaded file is incomplete (for example a 3000 lines text file will show only maybe 2000 lines at the first download, 1600 lines at the second download, and so on... and eventually, the file will download completely.

This issue happened with more than one user and with different tools.

Does anybody ever had this kind of issue? Or does somebody would have an idea of where to look to solve this problem?

Best regards,
Jean-François
