MATLAB is a high-level language and interactive environment that facilitates rapid development of algorithms for performing computationally intensive tasks.

Calling Bio-Formats from MATLAB is fairly straightforward, since MATLAB has built-in interoperability with Java. We have created a set of scripts for reading image files. Note the minimum supported MATLAB version is R2007b (7.5).


Download the MATLAB toolbox from the Bio-Formats downloads page. Unzip and add the unzipped bfmatlab folder to your MATLAB path.


As of Bio-Formats 5.0.0, this zip now contains the bundled jar and you no longer need to download loci_tools.jar or the new bioformats_package.jar separately.


Please see Using Bio-Formats in MATLAB for usage instructions. If you intend to extend the existing .m files, please also see the developer page for more information on how to use Bio-Formats in general.


In our tests (MATLAB R14 vs. java 1.6.0_20), the script executes at approximately half the speed of our showinf command line tool, due to overhead from copying arrays.


To use a newer version of Bio-Formats, overwrite the content of the bfmatlab folder with the newer version of the toolbox and restart MATLAB.

Alternative scripts

Several other groups have developed their own MATLAB scripts that use Bio-Formats, including the following:
