UK Biobank atlas - mesh generation

Generate meshes using the UK Biobank atlas (https://www.cardiacatlas.org/biventricular-modes/)

Install

Install with pip

python3 -m pip install ukb-atlas

or (latest version)

python3 -m pip install git+https://github.com/ComputationalPhysiology/ukb-atlas

or similarly with pipx

pipx install ukb-atlas

or (latest version)

pipx install git+https://github.com/ComputationalPhysiology/ukb-atlas.git

Usage

$ ukb-atlas --help
usage: ukb-atlas [-h] [-a] [-m MODE] [-s STD] [--mesh] [--char_length_max CHAR_LENGTH_MAX] [--char_length_min CHAR_LENGTH_MIN] outdir

Generate surfaces and meshes from UK Biobank atlas.

positional arguments:
  outdir                Directory to save the generated surfaces and meshes.

options:
  -h, --help            show this help message and exit
  -a, --all             Download the PCA atlas derived from all 4,329 subjects from the UK Biobank Study.
  -m MODE, --mode MODE  Mode to generate points from. If -1, generate points from the mean shape. If between 0 and the number of modes, generate points from the
                        specified mode. By default -1
  -s STD, --std STD     Standard deviation to scale the mode by, by default 1.5
  --mesh                Create gmsh mesh files from the generated surfaces.
  --char_length_max CHAR_LENGTH_MAX
                        Maximum characteristic length of the mesh elements.
  --char_length_min CHAR_LENGTH_MIN
                        Minimum characteristic length of the mesh elements.

For example, by running the following command

ukb-atlas data --mesh

The tool will generate the following files

data
├── AV_ED.stl
├── AV_ES.stl
├── ED.msh
├── EPI_ED.stl
├── EPI_ES.stl
├── ES.msh
├── LV_ED.stl
├── LV_ES.stl
├── MV_ED.stl
├── MV_ES.stl
├── PV_ED.stl
├── PV_ES.stl
├── RVFW_ED.stl
├── RVFW_ES.stl
├── RV_ED.stl
├── RV_ES.stl
├── TV_ED.stl
├── TV_ES.stl
├── UKBRVLV.h5
└── parameters.json

Which are surfaces for both the end diastolic (ED) and the end systolic (ES) shapes, the PCA atlas (UKBRVLV.h5) and the parameters used to generate the surfaces.
