[galaxy-dev] importing data from other public websites into galaxy

Hi, I wish to import data into my local instance of galaxy from another website. Kindly let me know how to achieve that and what all is required. I want to import data from a chemoinformatic database (mainly compound structures) into galaxy and run my own analysis tools on them.  Regards, Prasun Dutta MSc (Bioinformatics) School of Biological Sciences University of Edinburgh, UK
