If you have a lot of files to process through an app in the DE, and the app takes only 1 file at a time, what do you do? Do you manually start one job at a time? No, use an "HT Analysis Path List file". 

Step-by-step guide

  1. Go to the Discovery Environment and open the Data window.
  2. Use the "File" pull-down menu and select Create > "New HT Analysis Path List file".

  3. Drag and drop files that you want to use with an app into the new file.
  4. Save the file.
  5. Open your application (single file input only, not multiple file input).
  6. Drag and drop your HT Analysis Path List file in the box. 
  7. Configure the rest of the inputs for the app and launch the job.
  8. A separate job will run with each file on the HT Analysis Path List file, and the results for each file will be in a separate folder within the main job output folder in the Analyses window.
  9. Submitting jobs this way will start up to 8 simultaneous jobs in the DE.  You can submit up to 16 files at a time in an HT Analysis Path List file, but the maximum number of jobs that you can have running at a time in the DE is 8.
