Convert a file to NMI

To convert other file formats to the "Scientific Data File" file type, you need software like nVISION Data Management Software or a similar tool.


About NMI files

NMI files serve a dual purpose in the scientific and medical communities. They are primarily generated as either pulse oximetry data recordings from Nonin Medical, Inc. devices or as Atomic Force Microscopy (AFM) data files produced by NanoMagnetics Instruments equipment like the ezAFM. In both cases, the .NMI extension acts as a specialized container for highly accurate sensor readings. To read the medical data, professionals typically use nVISION software, while the microscopy data requires specialized AFM analysis suites.

The core disadvantage of the .NMI format is its proprietary, closed nature. Sharing these files with researchers, patients, or colleagues who do not own the exact software suite is practically impossible. The raw data is locked inside an undocumented binary or specialized encoded structure, making standard web browsers and typical office tools useless. Users frequently need to extract the underlying time-series data or image matrices to CSV, TXT, or standard raster images like PNG or TIFF for external analysis in Python, R, or Excel.

Because the encoding logic is guarded by the manufacturers, this file format is exceptionally difficult to open or convert directly. Standard online converters will instantly fail to parse the proprietary sensor payload. Often, only the original software can properly read, calibrate, or export the raw data. Despite this, you can drag and drop your .NMI file into convert.guru to identify the exact format structure, view internal text headers, and attempt a conversion if our analysis detects a supported embedded format.

Convert.Guru analyzes your NMI file, detects the exact format, and lets you read the text inside.

Users also converted SS5BOOK, DYS, SS5BIBLE, KM and MI files.

The NMI Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NMI converter.
