DICOM-Shaped Stream — No Preamble, No DICM Magic (.bin)
The identical element stream with the 128-byte preamble and the DICM magic stripped, which is how DICOM often arrives out of a network transfer or a database blob column. It is not a conformant Part 10 file and its content is entirely recoverable, so a reader should fall back rather than reject.
| Field | Value |
|---|---|
| Preamble | absent — the file starts at the meta group |
| DICM magic | absent |
| Is it Part 10? | no — Part 10 requires both |
| Is the content recoverable? | yes, every element after byte 0 is well formed |
| Seen in the wild | network transfers and databases that strip the preamble |

Testing contract
Expected to recover- Scenario
- Attempt a strict Part 10 parse, then fall back to parsing the file as a bare dataset starting at byte 0.
- Expected result
- The strict parse fails because DICM is absent at offset 128, while the fallback recovers all 27 elements and the same pixel data as the Part 10 file.
What is a .bin file?
A .bin file is a generic binary blob with no specific format — raw bytes whose meaning depends entirely on the producing application (firmware images, memory dumps, serialized payloads). The extension signals only 'not text.'
How to use this file
Use an example .bin file to test binary/hex viewers, file-type sniffing, octet-stream handling, and download pipelines that must not corrupt arbitrary bytes.
How to use this file for testing
“DICOM-Shaped Stream — No Preamble, No DICM Magic (.bin)” is a deterministic Novus Examples fixture for Scientific data, Serialization testing, Error handling. Citation catalogs (BibTeX, RIS), chemistry structures (MDL Molfile, PDB), and gridded binary data (NetCDF, FITS) — for testing reference managers, molecule viewers, and scientific-data loaders.
Documented properties for this file: BIN · 2,818 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Scientific fixtures are small, valid, and fully synthetic — no real organism, patient, sample, or observation. Point your parser or loader at the file and check it reads the documented records, variables, or headers; binary formats ship a readable twin or metadata listing for comparison.

- fitsFITS BLANK — Undefined Integer Pixels (.fits)Integer FITS images mark undefined pixels with the BLANK keyword, and BLANK is compared against the stored value before BZERO and BSCALE are applied. Scale first and the four undefined pixels turn into a perfectly plausible zero, which is the ordering bug this file exists to expose.
- fitsFITS Header-Only — Valid File With No Pixels (.fits)A completely valid FITS file consisting of one 2880-byte header block and no data unit, which the standard permits whenever NAXIS is 0. It separates readers that model the data array as optional from readers that treat 'no pixels' as corruption.
- fitsFITS Image — float32 with NaN and Inf Pixels (.fits)Single-precision FITS pixels including two NaNs, which is the only way the standard marks undefined data for floating BITPIX, plus one +Inf. Statistics computed without NaN-aware reductions come back as NaN for the entire frame.
- h5HDF5 Degenerate Shapes — Scalar, Zero-Length and Null (.h5)Five degenerate but entirely legal datasets — a rank-0 scalar, a zero-length vector, a (0, 5) array, a single-element vector and a NULL dataspace — plus an empty group. None of them is corrupt, and a reader that reports them as errors is the thing being tested.
- h5HDF5 Hard, Soft and Dangling Links (.h5)One array reachable under four names: itself, a hard link sharing its object address, a soft link resolved at access time, and a soft link pointing nowhere. A walker that counts names instead of object addresses reports four arrays and then crashes on the dangling one.
- h5HDF5 Numeric dtype Zoo — Every Width at Its Limits (.h5)Twelve datasets, one per numeric HDF5 type, each holding the extreme values of that type including the uint64 and int64 limits that do not survive a trip through a double. It is the fixture that exposes a reader which widens everything to float64 on the way in.
