Graphical User Interface for studying the growth of plant hypocotyl and root.
The software allows to select a collection of images following the growth of a plant organ. Several processing steps can be applied to segment hypocotyls on images, extract the contour, compute the Voronoi skeleton, measure curvilinear abscissa, identifies homologous positions on skeleton pairs, compute relative elongation rate, and finally display the result as a kymograph.
The software is developed for the Matlab platform.
Recent versions of Matlab provide a mechanism for easily install application. To install the KymoRod application, simply follow these steps:
- Download the latest version of the app (as a
KymoRod-x.y.mlappfile) - Start Matlab
- Click on the "Install App" icon, in the "Apps" tab of the ribbon interface
- Select the "KymoRod.mlapp" file, click "OK",
- You're done!
The program may alternatively be installed manually. This can avoid some dependencies of the Matlab installer. The procedure is as follows:
- Download the latest KymoRod archive (as a
KymoRod-x.y.zipfile) - Unzip in the folder of your choice
- Start matlab
- Change current directory to locate in the extracted directory
- Add the different paths, by typing
setupKymoRod - Launch the graphical user interface by typing
startKymoRod
The software code is divided into three parts
- the core sub-directory contains all the computational part of the program
- the userInterface sub-directory contains code for GUI and dialogs
- the lib sub-directory contains additional required libraries
The software was originally developed for the following study:
