About NMI files

The .NMI extension is shared by two distinct industries, creating frequent confusion.

  1. Nonin Pulse Oximetry Data: Generated by Nonin Medical devices (like the WristOx2), these files store continuous blood oxygen (SpO2) and heart rate recordings. They are proprietary binary files designed exclusively for nVISION software. Users typically need to convert these to PDF for medical compliance reports or CSV for raw data analysis, but direct access is locked without the licensed software.
  2. NanoMagnetics Microscopy Data: Created by NanoMagnetics Instruments for their ezAFM or hpAFM microscopes. These contain topographic or magnetic surface data. While the manufacturer software is standard, the open-source community prefers converting these to TIFF or PNG for publication using Gwyddion, which offers a free, powerful workaround to the official proprietary viewer.

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.
