What is SCMD What is SCMD ??

• SCMD is a collection of micrographs of SCMD is a collection of micrographs of budding yeast mutants.budding yeast mutants.

• Our image processing program, called Our image processing program, called CalMorph, , clips individual cells from clips individual cells from micrographs, then analyzes the micrographs, then analyzes the characteristics of them.characteristics of them.

• Currently following number of yeast mutants and Currently following number of yeast mutants and their micrographs are analyzed. their micrographs are analyzed. • Mutants analyzed: Mutants analyzed: 4,4954,495• Micrographs Processed: Micrographs Processed: 84,40784,407 (x (x
