[galaxy-user] question on galaxy reference genome window

Dear Galaxy members, I am new to galaxy and just installed galaxy on aws cloud. I am testing how it works and have the following question below: 1. I tried to test bowtie2 with the dataset I uploaded, however, the window for reference genome is very narrow and nothing from pull-down menu can be selected. When I omit that option to execute bowtie2, galaxy give error message for requesting reference genome. I am using hg19, should I upload myself? If so, how? 2. Same error happen for me to run fastqc --- the reference genome selection window is way too narrow and nothing can be selected Thank you very much for your inputs and helps! Kind regards, Kathryn
