minc-loader

The minc-loader is a NiiVue plugin that converts MINC format .mnc volumes into NIfTI volumes. It adapts code from brainbrowser library to read .mnc files (stored in both the older NetCDF and the more recent HDF5 structures).

Local Development

To illustrate this library, minc2nii.js is a node.js converter that can be run from the command line. The command npm run test runs some regression tests. The command npm run cli converts a MINC file to NIfTI from the command line. Finally, the command node ./src/minc2nii.js /path/to/minc/minc.mnc allows you to specify specific files to convert.

git clone [e-mail]:rordenlab/minc-loader.git
cd minc-loader
npm install
npm run test
npm run cli
node ./src/minc2nii.js ./tests/testData/ax.mnc

Local Browser Development

You can also embed this loader into a hot-reloadable NiiVue web page to evaluate integration:

git clone [e-mail]:rordenlab/minc-loader.git
cd minc-loader
npm install
npm run dev
