I am starting to really get the hang of customizing my new galaxy instance, and please just let me THANK YOU GUYS! However, I am also running into a problem. I am trying to link genome fasta files that i obtained through metazoa.ensembl.org. I created a library called "Genome Sequences" with sub-folders to house them. Everything was going fine until I tried to change the info on a couple so that they were fasta not so other randomly autoassigned type. Now I get this error msg when ever i try to browse ANY of the "Genome Seq" Library: Error attempting to display contents of library (Genome Sequences): 'NoneType' object has no attribute 'dataset'. I am running this instance using a postgresql backend but the default paste web-server since its mostly gonna me me and one or two other lab-mates using it. I can NOT figure out whats up.

And thanks for this priceless tool! Gus -- In science, "fact" can only mean "confirmed to such a degree that it would be perverse to withhold provisional assent." I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms. *-Stephen Jay Gould*
