Hello everyone, Firstly, I am beginner. I am a new Galaxy user that installed the Galaxy locally into my ubuntu (13.04) installed computer. Everything is working perfectly right now. Galaxy is really awesome. To learn the basics, I started the basic tutorial (Galaxy101 https://main.g2.bx.psu.edu/u/aun1/p/galaxy101) that helps too much. This tutorial consist a step for explaning "Compare Two Datasets" function. I did exactly everthing the instructor said however that module become red in History with following error: tool error An error occured with dataset: Unable to finish job (screenshot of error: http://i.imgur.com/xHqhK72.png) I wrote the bug report at end of the mail. Interestingly, when I press "View" button, I get the data that I wanted. However, any metadata is seen. So I can not see the final results on the UCSC browser. I replicate the same module at public server, it didn't gave an error. What might cause this kind of problem? Does reinstalling solve this problem? Would you please help me? Thank you everyone.
