Fichiers d'echantillon NII

NIfTI (.nii) files are common in neuroimaging and scientific imaging workflows, storing volumetric image data with spatial metadata in a compact binary container. Use sample .nii files to validate volume readers, header parsing, coordinate transforms, and cross-tool compatibility in analysis and medical-imaging pipelines.
