Hi all, a non-CCP4 question: Are there any good free programs for the design of one's own sparse matrix screens? I am looking for something in the lines of a set of mixtures of what gives you the best coverage of, say, seven variables with five states each in 96 experiments. Thanks, Jose. ************************************** Jose Antonio Cuesta-Seijo Cancer Genomics and Proteomics Ontario Cancer Institute, UHN MaRS TMDT Room 4-902M 101 College Street M5G 1L7 Toronto, ON, Canada Phone: (416)581-7544 Fax: (416)581-7562 email: [log in to unmask] **************************************
