Re: [galaxy-dev] Existing efforts to convert the QIIME pipeline to Galaxy?

Thanks Jim for giving this extensive update on how to improve the Qiime wrappers. We had contact about the Qiime wrappers before, and I have been using them in Galaxy on a weekly basis. Therefore I can say they have been proven to be very useful. I mainly edited the parameter and output sections of some configuration files, but all still use the wrapper script. The most important scripts are the split libraries and the workflow scripts (pick_otus_through_otu_table, alpha/beta diversity workflows). I use the Qiime scripts in a Galaxy Cloudman environment adjusted to a multicore server. Setup on EC2 shouldn't be a problem, although you need to place the requirement tag for all the needed dependecies on top of the xml file. I will have a look at the suggestions and I am willing to help to improve Qiime support for galaxy either by working on the configuration files or testing them out. So please keep me in the loop...

Message-ID: <4EFCC73C.7010709(a)umn.edu> Content-Type: text/plain; charset="iso-8859-1"; Format="flowed" It is easiest to generate tools for galaxy when the applications or scripts can take arbitrarily named input files and generate output to given path names. Input directories, output directories are very convenient on the command line, but more of a challenge when crafting a galaxy tool. That said, many applications require a wrapper script to work with in galaxy. Thank you for the consistent script_info[] help/usage syntax in the qiime scripts, which enabled me to generate a skeleton galaxy tool_config file for each qiime script. I had some time last spring to work on integrating qiime into galaxy. Unfortunately, I haven't had any time since to work on this. I put those partial results on the Galaxy Tool Shed: http://toolshed.g2.bx.psu.edu/ There's a continuing effort at George Mason University to incorporate qiime into galaxy tools, so you may want to ask them what they need. I started by generating galaxy tool_config files, e.g. align_seqs.xml, by using python to get the script_info[] from the qiime script: $ cat generate_tool_config.bash #!/usr/bin/env bash python $1 > ${1%.*}.help cat tool_template.txt | sed "s/__TOOL_BINARY__/${1}/" | python -i $1 -h > ${1%.*}.log (I'll attach tool_template.txt ) This generated skeleton tool_config .xml files that I could then edit as needed. ( http://wiki.g2.bx.psu.edu/Admin/Tools/Tool%20Config%20Syntax ) I originally was calling all qiime scripts from a tool wrapper: qiime_wrapper.py But, if a script can be called with any input filepaths and write its results to any filepaths, and only writes to STDERR when it fails, then you could call that script directly. When should you use a tool_wrapper or call the qiime script directly? Many of the qiime scripts could probably be called directly, especially if it can be called with arbitary input/output file pathnames. The reasons for using a tool wrapper may be if input/output needs to be manipulated, moved, renamed in order to be used by the qiime script. You'll also need a tool wrapper if the names or number of the output files can not be determined from the parameter settings. ( http://wiki.g2.bx.psu.edu/Admin/Tools/Multiple%20Output%20Files ) If your tool relies on a file ext to determine a format, you'll have to rename the input. ( Galaxy dataset pathnames will look something like: /<your_galaxy_file_path>/072/dataset_72931.dat ) The format/type of a dataset is stored in its metadata, so the tool_config can use that information, especially if a script can take muliple alternative input formats. A tool_wrapper can also be used to manage the stdout or stderr from a tool. Galaxy currently interprets any output on stderr as a failure. A couple changes in galaxy should make somethings easier than when I first attempted this: - galaxy now accepts dataset requests with sub directories. ( https://bitbucket.org/galaxy/galaxy-central/issue/494/support-sub-dirs-in-e… ) That means that output HTML files with links into sub directories can be left intact, with the html copied to the output dataset and the linked files to its "extra_files_path". - if you know the pathname of an output relative to the working directory, galaxy can copy it automatically to the output dataset using the from_work_dir attribute. ( see example in: https://bitbucket.org/galaxy/galaxy-central/src/21b645303c02/tools/ngs_rna/… ) Datatypes You may want to create new datatypes to make it easier for the user to correctly select inputs to a tool from previous outputs. For example, the qiime mapping file is a tabular file with specific requirements. I put a 'qiimemapping' datatype in lib/galaxy/datatypes/metagenomics.py and datatypes_conf.xml so an input could generate a select list containing only qiimemapping datasets rather than all tabular ones. Generating a configfile You can generate configfiles in the galaxy tool_config .xml file. The configfile is generated by the Cheetah interpreter just as the commandline is. see: alpha_rarefaction.xml The qiime_wrapper.py was patterned after the mothur_wrapper.py with some of the same wrapper params to handle run time determined output (perhaps not needed): --galaxy_datasets a comma separated list of regex:output_dataset the wrapper searches the working_dir and copies the file that matches the regex to the outout dataset if the exact pathname is known, use the "from_work_dir" attribute instead --galaxy_datasetid would be an output dataset id that would be used to dynamically create additional new datasets at job termination ( http://wiki.g2.bx.psu.edu/Admin/Tools/Multiple%20Output%20Files "Number of Output datasets cannot be determined until tool run") --galaxy_new_datasets a comma separated list of regex:datatype used to dynamically create additional new datasets at job termination --galaxy_new_files_path the galaxy dir for dynamically generated output datasets On 12/14/11 12:11 PM, Jose Carlos Clemente wrote: > Hi Jim, > > we just had a meeting to discuss ideas for a QIIME GUI, and were wondering how far did you manage to get with your plan to develop a QIIME wrapper for Galaxy.

We're very enthusiastic about hooking up QIIME with Galaxy, and definitely encourage you to work on it. It's something we've discussed doing, but no one in our lab is actively working on it. One particular use case that I've been thinking about would be to set up Galaxy/QIIME in our QIIME EC2 images so our EC2 users could access their images via the Galaxy web server.

Let me know if there are ways that we can help out, for example by giving you a list of what we believe are the most commonly used QIIME scripts so you can focus your efforts on those.

I'm writing a single script to call all the Qiime scripts, and generating a tool config (.xml) for each qiime script. Since the qiime scripts all contain a rather consistent script_info dictionary in the code, I wrote a script to generate an initial tool config from that script_info. I'm now starting the tedious process of editing those for each script. I'll attach the few I've started on.
