Alex,

I've looked into your question and there appear to be a couple of separate things. In this example, you gave your conditional the name "tool", which causes a certain set of problems. However, in your original example, the problem seems to be in how you were referring to the variable and also (possibly) the fact that the output should only exist when that particular options was selected.

I've included some sample code below, where the conditional is named "Xtool". This code has the following results when run with conditional parameters as specified:

1. Arguments: Xtool.cmd = "show-snps" Output: 1 output file, named "1 'Xtool.cmd': show-snps", is produced

2. Arguments: Xtool.cmd = "show-aligns" Xtool.extra1 = "IdR RRRRR" Xtool.extra2 = "IdQ QQQQQ" Output: 4 output files (listed below) are produced: 1 'Xtool.cmd': show-aligns 2 'Xtool.extra1': IdR RRRRR 3 'Xtool.extra2': IdQ QQQQQ 4 'Xtool.extra1, Xtool.extra2': IdR RRRRR, IdQ QQQQQ

The labels as specified for out_tool5 and out_tool6 caused errors.

Note that if you change the conditional name to "tool", the run equivalent to the two tests above results in: ⇝ NotFound: cannot find 'cmd' while searching for 'tool.cmd'

"tool" refers to the tool instance itself, not your conditional variable.

Successful code:

<tool id="tooltest2Xtool" name="Tool Test 2 (condition=Xtool)" version="0.1.0"> <description></description> <command interpreter="python"> tooltest2.py $Xtool.cmd #if $Xtool.cmd == "show-aligns" $Xtool.extra1 $Xtool.extra2 #end if $input_delta $cmd_extra $out_tool1 $out_tool2 $out_tool3 $out_tool4 ## $out_tool5 ## $out_tool6 </command> <inputs> <conditional name="Xtool"> <param name="cmd" type="select" value="show-snps" label="Select tool"> <option value="show-snps">show snps</option> <option value="show-aligns">show aligns</option> </param> <when value="show-aligns"> <param name="extra1" type="text" size="40" value="" label="IdR" help="FastA header ref sequence" /> <param name="extra2" type="text" size="40" value="" label="IdQ" help="FastA header query sequence" /> </when> <when value="show-snps" /> </conditional> <param name="input_delta" type="data" format="tabular" label="MUMmer delta file" /> <param name="cmd_extra" type="text" size="40" value="" label="Extra cmd line options" help="see specific cmd line options below for each tool" /> </inputs> <outputs> <data name="out_tool1" format="text" label="1 'Xtool.cmd': $ {Xtool.cmd}" /> <data name="out_tool2" format="text" label="2 'Xtool.extra1': $ {Xtool.extra1}"> <filter>Xtool['cmd'] == "show-aligns"</filter> </data> <data name="out_tool3" format="text" label="3 'Xtool.extra2': $ {Xtool.extra2}"> <filter>Xtool['cmd'] == "show-aligns"</filter> </data> <data name="out_tool4" format="text" label="4 'Xtool.extra1, Xtool.extra2': ${Xtool.extra1}, ${Xtool.extra2}"> <filter>Xtool['cmd'] == "show-aligns"</filter> </data> <!-- <data name="out_tool5" format="text" label="5 'Xtool.cmd.value_label': ${Xtool.value_label}" /> --> <!-- <data name="out_tool6" format="text" label="6 'Xtool.value_label': ${Xtool.value_label}" /> --> </outputs> </tool>

Let me know if this doesn't help.

Hi Jennifer,

sorry this doesn't work for me. If I use just the ${input} I get a reference to some memory location instead of the actual value. Therefore I was using the ${input.value_label} thing (on suggestion of the galaxy dev team :) ). But as mentioned this doesn't work for a conditional. Below I have a sample tool_xml just to illustrate the current tool_config and what I want to do. Using it like this give me a history box with something like: "Tool output <galaxy.tools.Tool instance at 0x6c186c8>". Obvious this is not what I want. Also using ${cmd} or ${tol.cmd} or ${tool.value_label} don't work. Any help or direction appreciated. Alex

Hi Alex,

Conditional usage/data return is possible, but not for the exact syntax that you are using. Modifying the query by removing the ".value_label" from the key should help:

change: ${input1.value_label} to be: ${input1}

Please let us know if this works or not and we can help more from there,

Best,

Hi All, Does someone know how to get the value of a type="select" param_name displayed in the output file label?

I know how to do it if its just a non-nested param setup-up using $ {input1.value_label} where the input1 is the select_name. But this fails if the select is inside a conditional..... From cheetah script I can call these values like IF $tool.cmd=="something":..... But whatever I try in the<outputs><data> fails (I though it to be $ {tool.cmd.value_label} but that complains on cmd not defined.... All possible iteration tried :( Snippet of a generalised tool.xml below. Any suggestions or hints where to get documentation on this syntax is welcomed! Alex
