What is a OIR file?

An OIR file is an image created by an Olympus FV3000 laser scanning microscope. It contains a 2D or 3D image of a scientific specimen. The image may be a complete image of the specimen, or it may be a portion of a composite image.

More Information

Scientists use the Olympus FV3000 to examine and create detailed, laser-scanned images of scientific specimens. For example, a biologist might use the FV3000 to image a portion of an animal's brain.

Images created using the FV3000 are saved as OIR files. Typically, each OIR file contains a complete image (which may be tiled to allow for detailed analysis). However, when creating an image larger than 1 GB, the FV3000 splits the image into multiple OIR files. To see the entirety of a split image, you must load all associated OIR files (e.g. for a split image that consists of two files, you must load both Example.oir and Example_00001.oir]).

How to open a OIR file

You can open an OIR file with OME Bio-Formats (multiplatform) or ImageJ (multiplatform). To open an OIR file with ImageJ, you must install the Olympus ImageJ plug-in.
