'''TIP''' This tool accept as inputs only Galaxy collections containing EAL templates.

**What it does?**
--------------------

This tool produce EML metadata from EAL templates.
This tool can be used in the continuation of the eml2eal tool.

**How to use it?**
--------------------
To use this tool, you can select, in your history a data collection with EAL templates made by the eml2eal tool. 
You can also select your own templates that you have to integrate into a Galaxy collection.

To do so you can select the **Upload file** tool, select the *Collection* tab, upload all your templates, click on the *Start* button to integrate the files to Galaxy and then click
on *Build*. You will need to choose a name and select *Create collection* to build a collection with your templates.
You also can upload your files to Galaxy, select them in the history by clicking the *Select items* button, click on the newly appeared box on the right and select *Build dataset list*.

 .. class:: infomark 
 
 Templates can be directly edited in Galaxy (view **eml2eal** tool for more information.)
 

You then have to select your collection in the upload box of the tool and click **Execute** to get your EML metadata.
