Hello Alex,

Do you mean a default dataset (that a user can modify or never modify) or default form entry data?


If default form entry data, then you can use the <param> tag set with "value", as described in this wiki:
http://wiki.g2.bx.psu.edu/Admin/Tools/Tool%20Config%20Syntax#A.3Cparam.3E_tag_set

Looking at existing tools that have default form data can provide good examples. For instance, the tool:

galaxy-central / tools / filters / remove_beginning.xml

See the content in <param  value="X"  /> line 5 below


 1  <tool id="Remove beginning1" name="Remove beginning">
 2    <description>of a file</description>
3 <command interpreter="perl">remove_beginning.pl $input $num_lines $out_file1</command>
 4    <inputs>
5 <param name="num_lines" size="5" type="integer" value="1" label="Remove first" help="lines"/>
 6      <param format="txt" name="input" type="data" label="from"/>
 7    </inputs>
 8    <outputs>
 9      <data format="input" name="out_file1" metadata_source="input"/>
10    </outputs>
12    <tests>
13      <test>
14       <param name="num_lines" value="5"/>
15       <param name="input" value="1.bed"/>
16        <output name="out_file1" file="eq-removebeginning.dat"/>
17      </test>
18    </tests>
19    <help>


Hopefully this helps. If not, write back, or even better, add in some clarification and post a brand new question/thread to the galaxy-...@bx.psu.edu mailing list (the best list for development questions):

Hi,

Is there a way to specify default data for a tool, maybe inside an xml?
