Tasks
- Test:
- Setup automatic tests of aseg and aparc atlases
- Setup an automatic group analysis test, using the buckner40
- Create unit tests for all in-use binaries that don't have one, and enhance the critical tests that do exist (create a wiki page listing each binary and how and whether its tested).
- Profile major binaries, identify important routines, and create unit tests for those.
Create a Dart server, with Dashboard, to receive nightly build and test results, for public web-page display
- Buy and setup a 64bit Intel Mac Pro, and setup as a build and test machine
- Quantify variability of results for a single subject due to algorithm randomness and platform differences
- Run valgrind on each binary to check for memory trampling
- Maintenance:
- Create VMWare Freesurfer virtual machine for Linux (so that freesurfer can run on Windows)
- Create a Mac Universal binary for Freesurfer (which is compatible with both powerpc and intel)
- Explore and mess with trying to get freesurfer to build in CMake, at least portions of it relating to Qdec
- Share 'baby-sitting' tasks of monitoring nightly build and test platforms.
- Bug fixing
