RDCRN Pedigree Drawing Tool

What is it?

The RDCRN DMCC currently supports two different pedigree editing tools. The RDCRN Pedigree Drawing Tool is based on pedigreejs. It allows for the creation, viewing, and editing of pedigrees within a browser. This pedigree can then be saved in various data formats, as well as SVG and PNG images. The second option is an external pedigree drawing module for REDCap, which can export pedigrees in the commonly used PED and DADA formats.
