Hi.
I'm still searching for a solution to this problem.
Currently we have to implement a tool to read the GTF file selected
via a from_data_table parameter and output a list of feature types.
Secondly we have a second tool that reads this file using a
from_dataset parameter so the user can select a specific datatype.
Not really ideal, I would prefer to do this in one tool if possible.
If I could reference the file chosen in the first select then this
should work.
For instance in the output data tags I can put label="${gtf.value}"
and it returns the name of the selected file from the datatable.
If I do the same in inputs section: <options from_file="${gtf.value}"
galaxy tries to find the file [galaxy_dir]/tool-data/${gtf.value}.
So the solution would ideally look like this:
<param name="gtf" type="select" label="GTF File --gtf">
<options from_data_table="pycrac_gtf"/> <!--link to .loc file with
gtf file per species -->
</param>
<param name="feature" type="select" label="Select feature">
<options from_file="${gtf.value}">
<column name="name" index="2"/>
<column name="value" index="2"/>
<filter type="unique_value" name="unique" column="1"/>
</options>
</param>
Hope that makes sense.
Thanks
Shaun

Hi Greg,
thanks for the suggestion. This line doesn't seem to work:
<options from_file="some_value">
Galaxy looks for a file at galaxy_dir/tool-data/some_value rather
than the value given in the .loc file
I would also like to be able to use the galaxy data tables rather
then referring directly to a .loc file.
Any ideas?

Hi Shaun,
This should be possible. It's been quite a long time since I
worked on tools, so maybe others can provide better assistance if I
am incorrect here. You'll need to have a conditional something
like the following ( not tested whatsoever ):
<conditional name="selected_file_select_list">
<param name="selected_gtf_file" type="select" label="Gtf
file by species">
<options from_file="some_file">
<column name="name" index="2"/>
<column name="some_value" index="1"/>
</options>
</param>
<when value="some_value">
<param name="values_from_selected_gtf_file"
type="select" label="Values from selected gtf file" />
<options from_file="some_value">
<column name="name" index="2"/>
<column name="some_value" index="1"/>
</options>
</when>
</conditional>

Hi Greg, I'm not sure if this answers my question. Using
options_from_file is fine if I want to refer to the same file each
time.
In this case I want the first select to choose which gtf file to
look at (by species) and the second select to pull options (gtf
annotation types) from this file.
So I would somehow have to reference the file using the first
parameter rather than giving a hard-coded path.
Is that possible?

Hello Shaun,
Use the 'from_file' option. The referenced file should be in the
~/tool-data directory in the Galaxy root. There are several
example tools in the distribution that use this option. Here is
the example code from the annotation profiler tool:
<param name="table_names" type="drill_down" display="checkbox"
hierarchy="recurse" multiple="true" label="Choose Tables to Use"
help="Selecting no tables will result in using all tables."
from_file="annotation_profiler_options.xml"/>
and here is an example from the microbial import tool:
<param name="kingdom" type="select" label="Select the Desired
Kingdom">
<options from_file="microbial_data.loc" startswith="ORG">
<column name="name" index="3"/>
<column name="value" index="3"/>
<filter type="unique_value" name="unique" column="3"/>
</options>
</param>

Hi,
I am trying to write a tool xml file and want to do the following:
I have a number of GTF files stored locally and referenced in a
data table. I give the user a drop down list of those available
using the following code:
<param name="gtf" type="select" label="GTF File">
<options from_data_table="gtf_files"/>
</param>
I then want them to choose an annotation type based on those
present in the selected gtf file above. It seems simple enough
to do this if the gtf file is in your history already:
<param name="feature" type="select" multiple="true"
label="Extract features">
<options from_dataset="gtf">
<column name="name" index="2"/>
<column name="value" index="2"/>
<filter type="unique_value" name="unique" column="2"/>
</options>
</param>
But is there a way to query locally stored files via
datatables/.loc files to pull out options when the file is
dynamically chosen by a different parameter?
This code is also wrapped in a conditional, I'm not sure if that
will affect anything.
Thanks
Shaun
