See this link for an important summary of my AI/FROC research websites.
This repository contains a file SetupV4.2.1.zip which, when unzipped, contains the installation files for Windows JAFROC software version 4.2.1. This is the latest software that used to be downloadable from my now defunct website www.devchakraborty.com. This software is now replaced (and extended) by the RJafroc package. It is made available here as many have found it to be particularly easy to use. It was last tested on Windows 8 but I am no longer maintaining it. Click on the SetupV4.2.1.zip file to download it.
