Included Projects

AzureBatchDependenciesStorage includes only one project:

• AzureBatchDependenciesStorage - Azure Batch Cloud Assembly.

Building the Cloud Assembly

You need to specify the access details of Azure storage account associated with your azure batch app service. You will find the details on how to find out this azure storage details here ( http://sarkar.azurewebsites.net/2015/03/16/uploading-large-executable-on-azure-batch-service-app-management-portal/ ). To build the cloud assembly zip file:

1. Add Azure Storage access details to DownloadFile method in TaskProcessor.cs file in the AzureBatchDependenciesStorage project.
2. Build the AzureBatchDependenciesStorage project.
3. Open the output folder of the AzureBatchDependenciesStorage project.
4. Select all the DLLs (and optionally PDB files) in the output folder.
5. Right-click and choose Send To > Compressed Folder.

Getting the Application Image

To build the application image zip file:

1. The dummy test application image ( mri-processing-dummy.zip ) is included in this github repository.

Uploading the Application to Your Batch Apps Service

Expected Result of the Application once Job is finished

1. Final Job output is a file named completion.txt which indicates that job is done
2. Each of the four copies the content of input files to new output files ( resliced_tissue.nii, resliced_brain.nii ,skull-stripped_tissue.nii and skull-stripped_brain.nii ).
