This topic describes how to create a run task using a gene application in a workspace.
Step 1: Select an application version
In the application configuration of your workspace, navigate to the gene analysis application and click Run.
Step 2: Set run options
From the application version drop-down list, select an application version or tag.
Call-Caching: Specifies whether to reuse the results of previous computing jobs. For more information, see Run options.
Task execution directory: The default directory is the analysis/ directory in the OSS Bucket attached to the current workspace. The final and intermediate results are uploaded to this directory.
Delete intermediate results: Specifies whether to delete the intermediate results of the run task and retain only the final flow outputs. If you delete the intermediate results, the task result cannot be used for the Call-Caching feature in subsequent tasks.
Copy final results and result output location: If you select this option, the final output is copied to the specified directory. By default, the result files retain the original workflow directory structure. If you select Use relative path, only the final files are copied to this directory.
Click the system-recommended parameters drop-down list to select a set of pre-filled application parameters. These parameters are configured when the application is created (see Step 4).
Step 3: Provide input parameters for the application run
Input parameters have different types that are defined in the application. You must provide a valid value for each required parameter.
File: An OSS file path, such as oss://bucket/dir/to/file or oss://bucket/dir/.
String: A character string, such as "abc".
Float: A floating-point number, such as 1.2.
Int: An integer, such as 10.
Boolean: A Boolean value, such as true or false.
Array[X]: A list of values of one of the primitive data types listed above.
Pair[X,Y]: A tuple of two primitive data types, such as ("bam", "bam_index").
For more information about data types, see the Workflow Description Language (WDL) Syntax Specification.
The platform provides a file selector for File-type inputs. You can select OSS files from the current region or files from public datasets provided by the platform.
You must provide valid values for all required parameters to create a run task.
Step 4: (Optional) Use system-recommended parameters
When you develop an application, you can provide different sets of run parameters for various scenarios. This allows users to analyze gene data using parameters that align with best practices.
After you select a set of system-recommended run parameters, the parameter input fields are automatically populated. You can then modify the parameter values as needed.
Step 5: Creation successful
After the task is created, the platform automatically redirects you to the Runs page. On this page, you can view your previous run tasks. Click a task name to open the task details page, where you can view the run status, execution progress, and task log information.
If the task that you created does not appear on the Runs page, refresh the page.
