Re: [galaxy-dev] Creating multiple datasets in a libset

5 Jun 2013

      Hi Rob,

Thank you for providing these classes.  I have downloaded these classes and tried to get to work for what I need.  I basically would like to be able to load multiple files (FASTq(s), bed(s)) files into new history and run a certain workflow (many steps).  I could not get around the idea of how to associate the loaded files to the workflow steps knowing that I will have multiple bed(s) files and they will have different names each time.  So this lack of understanding in addition to unfamiliarity with python could be the issue here.

Here is the error I keep getting running your classes:

Traceback (most recent call last):
  File "watch_multifiles.py", line 285, in <module>
    main(api_key, api_url, in_folder, out_folder, data_library, workflow )
  File "watch_multifiles.py", line 248, in main
    galaxyHistory = gwf.execute_workflow(workflow_id, step_id_mapping,
history_name)
  File "watch_multifiles.py", line 158, in execute_workflow
    ds_map[step_id] =  step_id_mapping[label]
KeyError: 'Input Dataset'

And here is what I did:

1.        I uncommented the main section as follow:

def main(api_key, api_url, in_folder, out_folder, library_name, workflow_id):

#

#     EXAMPLE: api_key  http://local:8080/api/ /tmp/API/ /tmp/API/done "API imports" wf_id

     history_name = library_name + '-hist'

#

     gl = GalaxyLibrary(api_key, api_url, library_name )

     fileset = ['/tmp/API/temp.bed', '/tmp/API/seq.fasta']

     gl.upload_files(fileset);

     libset =  gl.get_libset()

#

#     #Map workflow input labels with input files

     step_id_mapping =  get_map(libset)

     #Add Archived Datasets

#

     gwf = GalaxyWorkflow(api_key, api_url, workflow_id)

     print("Hi there ***************************",history_name,   workflow_id)

     galaxyHistory = gwf.execute_workflow(workflow_id, step_id_mapping, history_name)

#

     #Map the output label with a filename to export the results once the run is completed

     copyFileMap = {"output1":"output_file.txt"}

     gh = GalaxyHistory(api_key, api_url, history_id)

     gh.export_results("/tmp/API/", copyFileMap)

#

#

#

#Map a workflows input labels to the file ids of input files. Assumes you've labeled your workflow inputs accordingly.

def get_map(libset):

    ds_map = {}

    #Add dynamic data sets

    for ds in libset:

        if ds['name'].endswith("bed"):## changed from "vcf"

                                    print("Got bed file:",ds)

                                    ds_map['INPUT_LABEL_1'] = { 'src' : 'ld', 'id' : ds['id'] }    #The first file you uploaded

        if ds['name'].endswith("fasta"):##changed from "bed"

                                    print("Got fasta file:",ds)

                                    ds_map['INPUT_LABEL_2'] = { 'src' : 'ld', 'id' : ds['id'] }    #The second file you uploaded

    #Add Archived Datasets

    ds_map['INPUT_LABEL_3'] = { 'src' : 'ldda', 'id' : '<id_to_an_input_file_already_stored_in_the_data_library>'}

    return ds_map

#

#if __name__ == '__main__':

#     main()

if __name__ == '__main__':

    try:

        api_key = sys.argv[1]

        api_url = sys.argv[2]

        in_folder = sys.argv[3]

        out_folder = sys.argv[4]

        data_library = sys.argv[5]

        workflow = sys.argv[6]

    except IndexError:

        print 'usage: %s key url in_folder out_folder data_library workflow' % os.path.basename( sys.argv[0] )

        sys.exit( 1 )

    main(api_key, api_url, in_folder, out_folder, data_library, workflow )

2.       I created a simple workflow that takes two input files (bed and fasta).  I changed the labels to what you suggested in your comment "INPUT_LABEL_1" and "INPUT_LABEL_2"

3.       Then I ran it (similar way to the example_watch_folder.py)

The two files get loaded to the data library but then right away I get the above error.

I appreciate your feedback in regards to this.

Regards,
Hakeem

Hi Niel,

I've attached my wrapper classes I'm using for the Galaxy API which allows me to upload multiple files. This was based on the watch_folder example. There is also a mapping mechanisms to map input and output files to their workflow labels. See the commented section below for some hints on how to use it

Hi Guys,

                #TODO Handle this better, but the datatype isn't always

Hi Dannon,

I've written some code to (i) query a dataset to ensure that it's been
uploaded after a submit and (ii) to ensure a resulting dataset has been
written to the file.

*#Block until all datasets have been uploaded*
libset = submit(api_key, api_url + "libraries/%s/contents" % library_id,
data, return_formatted = False)
for ds in libset:
    while True:
        uploaded_file = display(api_key, api_url +
'libraries/%s/contents/%s' %(library_id, ds['id']), return_formatted=False)
        if uploaded_file['misc_info'] == None:
            time.sleep(1)
        else:
            break

*#Block until all result datasets have been saved to the filesystem*
result_ds_url = api_url + 'histories/' + history_id + '/contents/' +
dsh['id'];
while True:
    result_ds = display(api_key, result_ds_url, return_formatted=False)
        if result_ds["state"] == 'ok':
            break
        else:
            time.sleep(1)

Yep, that example filesystem_paths you suggest should work fine.  The
sleep() bit was a complete hack from the start, for simplicity in
demonstrating a very basic pipeline, but what you probably want to do for a
real implementation is query the dataset in question via the API, verify
that the datatype/etc have been set, and only after that execute the
workflow; instead of relying on sleep.

Hi Dannon,
Thanks for the response. Sorry to be pedantic, but just to make sure that
I understand the interpretation of this field on the other side of the API,
I would need to have something like the following:
data['filesystem_paths'] = "/home/me/file1.vcf \n /home/me/file2.vcf /n
/home/me/file3.vcf"
I assume I should also increase the time.sleep() to reflect the uploading
of extra files?
Cheers,
Rob

Hey Rob,
That example_watch_folder.py does just submit exactly one at a time,
executes the workflow, and then does the next all in separate transactions.
 If you wanted to upload multiple filepaths at once, you'd just append more
to the ''filesystem_paths' field (newline separated paths).

I'm looking at example_watch_folder.py and it's not clear from the
example how you submit multiple datasets to a library. In the example, the
first submit returns a libset [] with only a single entry and then proceeds
to iterate through each dataset in the libset in the following section:
data = {}
data['folder_id'] = library_folder_id
data['file_type'] = 'auto'
data['dbkey'] = ''
data['upload_option'] = 'upload_paths'
*data['filesystem_paths'] = fullpath*
data['create_type'] = 'file'
libset = submit(api_key, api_url + "libraries/%s/contents" %
library_id, data, return_formatted = False)
time.sleep(5)
for ds in libset:
if 'id' in ds:
wf_data = {}
wf_data['workflow_id'] = workflow['id']
wf_data['history'] = "%s - %s" % (fname,
workflow['name'])
wf_data['ds_map'] = {}
for step_id, ds_in in workflow['inputs'
].iteritems():
wf_data['ds_map'][step_id] = {'src':'ld',
'id':ds['id']}
res = submit( api_key, api_url + 'workflows',
wf_data, return_formatted=False)
