Persistence analyzes images of polymers to determine their bending persistence length. Details can be found in the published paper Graham JS, McCullough BR, Kang H, Elam WA, Cao W, and De La Cruz EM (2014), Multi-Platform Compatible Software for Analysis of Polymer Bending Mechanics, PLoS ONE 9(4): e94766. doi:10.1371/journal.pone.0094766 . The software is copyrighted by the De La Cruz lab at Yale, but is free to use and distribute for non-commercial purposes. Please reference the paper when you use the software to analyze your data.
The software is created in MATLAB, but can be run without MATLAB using the MATLAB Runtime application that may be downloaded for free from the MathWorks website (see link below). Sample data, more information, and and a tutorial are included in the zip file. Also included in the software package is a document detailing ImageJ procedures for preparing the correct images for Persistence software. Updates to the software will be posted as available.
The newest version is available to be download below! The previous versions are not available to be download anymore, but if you want, you can send an request email to email@example.com.
