Hi, Len.<div><br></div><div>Please take a look at <a href="https://bitbucket.org/galaxy/galaxy-central/wiki/CompositeDatatypes">https://bitbucket.org/galaxy/galaxy-central/wiki/CompositeDatatypes</a> and see if that might help?</div>
<div><br></div><div>You can copy or create arbitrary files in the directory stored as the html datatype&#39;s extra_files_path. </div><div>To make them visible and accessible to the user, write a list of href links in a valid html page of the html datatype - the display automagically deals with looking in the extra_files_path to find them. </div>
<div><br></div><div>Composite objects are also great for organizing messing tool outputs for display and might be what you are looking for to pass bunches of files to tools. Note that since your tools will need to look in the html file&#39;s extra_files_path, that needs to be passed in to your tools on the command line. </div>
<div><br></div><div>Hope this helps get you going.</div><div><br></div><div><br></div><div>Fri, Oct 22, 2010 at 8:21 PM, Len Trigg <span dir="ltr">&lt;<a href="mailto:len@realtimegenomics.com">len@realtimegenomics.com</a>&gt;</span> wrote:</div>

<br>
I have just downloaded galaxy, got up and running with a local installation. I&#39;d like to have a crack at integrating some of our tools into the system.<br>
<br>
To start off with, we use a data format that is actually a directory containing multiple (variable number of) files and subdirectories. Is it possible to define a datatype that treats this directory as a single object in terms of using it as tool inputs and outputs?<br>

<br>
It seems like I could define a datatype corresponding to a zipped version of the directory (and this would be useful for uploading), but once it&#39;s uploaded I don&#39;t want the tools to be packing and unpacking zipfiles all the time.<br>

<br>
<br>
Cheers,<br>
Len.<br>
