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 ?

Well, I am tempting to say: 'everything' is possible with galaxy.
Although I do agree that Galaxy is a great tool :), one of the things Jerome asked is actually not possible: iterating over a list of files is currently a no go unless you want to click yourself into a sick leave due to RSI. This is something I would love to see as in some of our experiments we generate big collections of files. For example we use LC separation before MS usually generating something like 12 * 12 = 144. Manually uploading 144 files for processing in Galaxy is not fun. As a workaround we can sometimes merge the data from the fractions before uploading, but in that case you easily loose the link between the identified peptides and which fraction it was derived from, so this is suboptimal... So, more complex workflows with splitting, merging, looping, etc. are not (yet) possible with Galaxy as far as I know, but because Galaxy does not do this complex stuff, you don't need a manual to get started: KIS :). Cheers, Pi
Galaxy is so brilliant, because, you can easily modify the existing tools and you can add pretty much any tool you want (as long as it can be called from the command line). In our local Galaxy installation, we have added several tools which rely on files outside of the galaxy directory tree.
Storing results in user home directories might be a little bit tricky, but I don't see major problems, as long as the server on which galaxy runs has access to the home directories, each home directory has a designated area with write permission for the 'user' galaxy and the individual users are logged in when they use galaxy....you will need to discuss this with your sysadmin.
Once you have been using galaxy, you will probably realize, that you don't want to store results in home directories...especially if you work with large files (eg NGS). Take advantage of Galaxy, where every user has his/her own history (i.e. the datasets) on a central server.
Enough "blabla" from my site - just download and install Galaxy. And you will soon realize its potential.
