pl-spleendata
is a ChRIS FS plugin which downloads an exemplar spleen dataset useful for training and inference experiments.
This is a simple FS plugin suitable for training and inference on 3D spleen NiFTI volumes, as part of the MONAI spleen segmentation exemplar notebook. FS plugins are suitable as root nodes of ChRIS compute trees, i.e. the data node from which all processing continues. If you need to inject spleen data into a non-root tree node, use the companion DS spleen data node.
By default, the download is pretty big -- 1.2Gb, so make sure you have time and space. It is possible to post-download prune this. For example, if you are only interested in training, you can use a --trainingOnly
flag which will prune out the 43Mb of testing NiFTI volumes. Conversely, if you are just interested in inference, the --testingOnly
will remove the post download 1.2Gb of training data, saving lots of space.
You still need to download the whole set, however, before you can prune.
pl-spleendata
is a ChRIS plugin, meaning it can run from either within ChRIS or the command-line.
If you have checked out the repo, you can simply run spleendata
using
source venv/bin/activate
pip install -U ./
spleendata output/
Alternatively, you can just do a
pip install spleendata
to get directly from PyPI.
The recommended way is to use Apptainer (a.k.a. Singularity) to run pl-spleendata
as a container:
apptainer exec docker://fnndsc/pl-spleendata spleendata [--args values...] output/
To print its available options, run:
apptainer exec docker://fnndsc/pl-spleendata spleendata --help
spleendata
, being a ChRIS FS plugin, only requires one positional argument: a directory that will contain the output data. Simply create an empty output
.
mkdir output
apptainer exec docker://fnndsc/pl-spleendata:latest spleendata [--args] incoming/ outgoing/
Instructions for developers.
Build a local container image:
docker build -t localhost/fnndsc/pl-spleendata .
Mount the source code spleendata.py
into a container to try out changes without rebuild.
docker run --rm -it --userns=host -u $(id -u):$(id -g) \
-v $PWD/spleendata.py:/usr/local/lib/python3.11/site-packages/spleendata.py:ro \
-v $PWD/in:/incoming:ro -v $PWD/out:/outgoing:rw -w /outgoing \
localhost/fnndsc/pl-spleendata spleendata /incoming /outgoing
Run unit tests using pytest
.
It's recommended to rebuild the image to ensure that sources are up-to-date.
Use the option --build-arg extras_require=dev
to install extra dependencies for testing.
docker build -t localhost/fnndsc/pl-spleendata:dev --build-arg extras_require=dev .
docker run --rm -it localhost/fnndsc/pl-spleendata:dev pytest
Steps for release can be automated by Github Actions. This section is about how to do those steps manually.
Increase the version number in setup.py
and commit this file.
Build and push an image tagged by the version. For example, for version 1.2.3
:
docker build -t docker.io/fnndsc/pl-spleendata:1.2.3 .
docker push docker.io/fnndsc/pl-spleendata:1.2.3
Run chris_plugin_info
to produce a JSON description of this plugin, which can be uploaded to ChRIS.
docker run --rm docker.io/fnndsc/pl-spleendata:1.2.3 chris_plugin_info -d docker.io/fnndsc/pl-spleendata:1.2.3 > chris_plugin_info.json
