VIDS File Naming (v1.0)

VIDS uses BIDS-inspired sub- and ses- prefixes and sidecar JSON pairing conventions.

General pattern

sub-<ID>_ses-<ID>_<modality>_<suffix>.<extension>

Required pairs

• *_img.nii.gz (or .nii) MUST have *_img.json.
• *_seg.nii.gz (or .nii) MUST have *_seg.json.
• JSON-only annotation files (*_cls.json, *_bbox.json, *_lm.json, *_roi.json) are their own sidecars and require no paired NIfTI.

Common suffixes

• _img imaging volume.
• _seg segmentation mask.
• _bbox bounding boxes (JSON).
• _cls classification labels (JSON).
• _lm landmarks (JSON).

Modality codes (examples)

• ct, mr, xr, us, mg, pt, nm, path (custom allowed if documented).
