Searches and displays molecules and proteins well. The cartoon and trace views are only for proteins. It'd be nice if you could zoom.
One of my top regularly used apps.
Have been using Jmol and JSpecView for last month. In proton NMR predicted data, -OH, -NH and -NH2 groups do not appear in spectral data. Why? For calculation parameters for proton and carbon-13 predictions, have not been able to vary 400 MHz proton and 100 MHz proton-decoupled carbon-13. Why? Tried 1H and 13C predictions of BioTopics streptomycin.mol with success as of 11/16/2016. Not bad!
