[galaxy-user] Novice questions

Hi, I'm currently using ergatis as workflow manager, and I'm looking at the differences between ergatis and galaxy. In order maybe to migrate to galaxy. One really important feature to me is the ability of ergatis to iterate against file liste. I haven't seen anything like this in galaxy, am I mistaking ? Other point there is a way to make galaxy using local files instead of importing all files on the server ? And finaly I was wondering if there is a way to configure galaxy, so the outputs are stored to the ldap-user home directory ? thanks for your reply, Jerome
