IJ_Rhizo is an ImageJ macro for the batch processing of scanned images of root samples physically separated from soil by washing. IJ_Rhizo automatically generates root length and radius measurements. Being based on a public domain, Java image processing package, IJ_Rhizo is free of charge and platform-independent. IJ_Rhizo offers a simple GUI so that it can be used by end-users with limited computer literacy. This GUI allows to customize: image resolution; the size of image border to be excluded from processing; background particle cleaning; root length correction including the Kimura estimator; and the choice of automatic versus user-defined thresholding. In addition, the macro is also fully modifiable to accommodate the specific needs of more advanced users. IJ_Rhizo generates, in addition to the main “ResultAll.txt” output file and for each image analyzed, a root radius distribution file, stored as a text file and named using the input image name exclusive of the original extension.
