Questions & Answers
ND2 files: Frequently Asked Questions
What are ND2 files?
ND2 is the proprietary file format produced by Nikon NIS-Elements, the software that drives Nikon confocal and widefield microscopes. The name comes from the N-dimensional structure of the data: one ND2 file can store a multichannel fluorescence acquisition, a z-stack of focal planes, a time-lapse series and several stage positions at once, together with metadata such as objective, exposure time, pixel size and channel assignments. ND2 files are widely used in cell biology and neuroscience labs, and since the format is tied to Nikon software, researchers typically convert them to TIFF or PNG when images need to be opened elsewhere, shared with collaborators or used in publications.
