Hi. For some time now I've used RasMol and Chime in introductory biology lab for molecular visualizations and basic analysis of proteins. It seems that RasMol is not compatible with new Macs, and there are some excellent Chime tutorials that are not compatible with Firefox or IE. My Mac students are using iMol. Other than downloading Netscape 4.x for the PCs, I'd appreciate suggestions on more recent software that is compatibile with Chime tutorials and will allow protein analysis and movie making, and maybe have more capabilities. Thanks. Joel Kowit Biology Emmanuel College kowitj at emmanuel.edu
