ITK/Release 4/Testing Data

The Challenge

• Data used for testing can be large.
• Data should not be stored along with the source code
• Data files change along with the evolution of the code
  • So we have to track their specific versions.
• Adding new files should be quick and easy, ideally with a single command line
• There should be a way to pull down the testing data corpus as a whole. You should be able to run CTest without an Internet connection.

MIDAS Proposal

• Store ITK Testing Data in MIDAS
• Download it at run time during ITK testing.

Data on MIDAS

MIDAS - CMake

The file

   MIDAS.cmake 

contains a CMake function that will download specific files and put them in a given directory.

This file will be in the directory

   ITK/CMake

How to find Checksum files

• Go to the MIDAS page of the image of your interest
  • From: http://midas.kitware.com/community/view/7
    • For example, the image "cthead1.png" can be found at: http://midas.kitware.com/item/view/258
• Click on the check-box "Advanced View" at the top of the page.
  • The checksums of individual files will be displayed under the filenames
  • A "Download MD5 Key File" link will be shown in front of the checksum number
• Click on the "Download MD5 Key File" and save the file in the directory
