Who developed GiA Roots?

GiA Roots was developed as a collaboration between the Weitz group at Georgia Tech, the Harer group at Duke University and the Benfey laboratory at Duke University.

The development of GiA Roots was made possible by grants from NSF PGRP 0820624, DARPA HR0011-09-1-0055 and the Burroughs Wellcome Fund.

Is GiA Roots free?

Yes, GiA Roots is free for use - in academic and non-academic settings. For the specific legal stuff, see the license on the download page. If you want to consider a donation to support future developments of root network analysis tools, please contact Joshua Weitz for more information -- noting that Georgia Institute of Technology is a non-profit institution.  

Who can use GiA Roots?

Anybody. You do not need any programming or image analysis experience.

It designed to be simple and user friendly.

Advanced users can develop add-ons to the software, please see the manual for more details.

What types of images work best in GiA Roots?

GiA Roots accepts images in JPG, TIFF, BMP and other standard formats. We recommend the use of images in which there is a strong contrast between root system and background. The background can be dark and the roots light, and vice-versa.

I've got noise in my images, is that ok?

The answer is: it depends. GiA Roots has a number of automated tools, including cropping and thresholding that can assist in identifying roots and estimating root system architecture traits. However, we cannot guarantee that the built-in methods are suitable for the level of noise in every data set.

Do you plan to release future versions of GiA Roots?

Yes, that's the plan. We also welcome your input, please direct emails to Joshua Weitz.
