This is the caBIG CTMS Compatibility Grading SIG. The purpose of SIG is to evaluate legacy, vendor-based, and emerging caBIG modules for compatibility with the caBIG guidelines for bronze, silver, and gold level caBIG compatibility, and to conduct a 'gap analysis' to continually refine and enhance the compatibility guidelines. The SIG is led by Teri Melese (University of California San Francisco) and John Speakman (Memorial Sloan-Kettering Cancer Center, NY).
