TODO

• resolve fw-beta gear install error

Error: writing blob: determining upload URL: http: no Location header in response

• break up Program/dostat.m and add tests using input/trunc
  • optimize/vectorize esp. std command? surprisingly slow
  • profile against matlab runtime - switch to ML compiled version if octave is much slow
• slim docker container: build octave without Xorg or java (likely to be useful for other containers later)
• add subset of stats.json to FW DB
• create script (outside of flywheel) to plot stats across time

Testing

make test
make test-docker

Using octave %!test in-file tests. See bottom of Program/readshimvalues.m.

Editiing

• Makefile guides through steps

  • see .docker then .gear for packaging
  • mess of other files for .gear-run.txt with various input files setup (download input zip and setup config.json)
    • fw-beta is used for gear setup
    • this started from hello-world gear
    • Program/run.py still used for flywheel entry (sets up input/ and output, eventually handles DB)

• bump version in manifest.json: "version": and "custom": { "gear-builder": { "image": "npac/mrrcqa:1.0.20240822" } } current match.

Noteworth files

file	desc
Program/QC.m	octave script, docker entrypoint into @chms matlab QC code
Program/run.py	flywheel-aware entrypoint for gear. unzips and dispatches to QC.m
Makefile	make interface to building and testing recipes
Dockerfile	describes software dependencies, recipe for container
config.json	fw-beta gear run input. built with Makefile

Interfacing with Flywheel

• repo init with copy from https://gitlab.com/flywheel-io/scientific-solutions/tutorials/Gear-Building-Tutorial/-/tree/hello-world

• for archive as file type in manifest.json, see https://docs.flywheel.io/User_Guides/user_file_types_in_flywheel/ (c.f nifti)

• clasification qa picked form list on https://flywheel-io.gitlab.io/tools/app/cli/fw-beta/gear/upload/
