Hi, What I am trying is, A) to write an exec_after_process for tool1(Scatterer tool). This tool1 gives multiple outputs(in the form of files names generated by Galaxy). ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ scatterer_postprocess.py def exec_after_process(app, inp_data, out_data, param_dict, tool, stdout, stderr): print "Collected Dataset[Primary] is %s"% param_dict.get('__collected_datasets__')['primary']['output1']; Output: Collected Dataset[Primary] is {'output2': <galaxy.model.HistoryDatasetAssociation object at 0xb0648ac>, 'output3': <galaxy.model.HistoryDatasetAssociation object at 0xb15170c>, 'output4': <galaxy.model.HistoryDatasetAssociation object at 0xaf499ac>} ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ I could see these values successfully. Next, B) I wanted to view these multiple values in the exec_prejob hook of tool2(Gatherer) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ gatherer_prejob.py def exec_before_job(inp_data, out_data, param_dict, tool): print "******************* collected dataset is %s"% param_dict.get('__collected_datasets__')['primary']['output1']; Output: TypeError: Error in 'Gather' hook 'exec_before_job', original message: exec_before_job() got multiple values for keyword argument 'inp_data' ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ I am not very savy with Python for now. Can someone point me out to any possible resolution to this issue. The reason I am writing these hooks is to read the multiple inputs in tool2 thrown out by tool1. Thank you for your time.

Hi, Currently I am building a workflow which splits a file into multiple chunks and then recreates it back into one. Following the document on https://bitbucket.org/galaxy/galaxy-central/wiki/ToolsMultipleOutput, I wrote the following code. The following is my Splitter tool: <tool id="sc" name="sc" version = "1.0.0" force_history_refresh="True"> <description> My tool 1 </description> <requirements/> <command>java -cp /Splitter1.jar /Common.jar SplitterModule $input $output1 $output1.id $__new_file_path__</command> <inputs> <param format="txt" name="input" type="data" label="reads"> <label>Reads</label> </param> </inputs> <outputs> <data format="interval" name="output1" metadata_source="input"/> </outputs> <help> </help> </tool> The following is my Integrator tool: <tool id="gt" name="gt" version = "1.0.0"> <description> My Tool 2 </description> <requirements/> <command> java -cp Integrator1.jar:Common.jar IntegratorModule $input $output </command> <inputs> <param format="interval" name="input" type="data" label="pp"> <label>File Name</label> </param> </inputs> <outputs> <data format="text" name="output"/> </outputs> <help> This tool reads the reads.pp.txt file and creates smaller sized batches of it. </help> </tool> When I try to connect and run the workflow, this is what happens: 1. The files with the names generated from the parameters are created in the tmp folder temporarily 2. Then these are removed and converted to .dat files and placed in database/files/000 folder with the galaxy generated numbers file names.(eg. dataset_89.dat) 3. However, when I check the parameters in the IntegratorModule program, I receive new dataset files generated by Galaxy and NOT the ones which were created and should have been passed from the Splitter module Is there a format I need to follow when writing the Integrator Module's input parameters? Any pointer to any document which mentions this will be helpful. Thank you for your time.
