CINEMA is a new editor for manipulating and generating multiple sequence alignments. The program provides both an interface to existing databases of alignments on the Internet and a tool for constructing and modifying alignments locally. It is written in Java, so executable code will run on most major desktop platforms without modification. The implementation is highly flexible, so the applet can be easily customised with additional functions; and the object classes are reusable, promoting rapid development of program extensions. Formerly, such extended functionality might have been provided via browser plug-ins, which have to be downloaded and installed on every client before loading data. Now, for the first time, an applet is available that allows interactive client-side processing of an alignment, which can then be stored or processed automatically on the server. The program is embedded in a comprehensive help file and is accessible both as a stand-alone tool on UCL's Bioinformatics Server; http:/(/)www.biochem.ucl.ac.uk/bsm/dbbrowser+ ++/CINEMA2.02/, and as an integral part of the PRINTS protein fingerprint database. Exploitation of such novel technologies revolutionises the way users may interact with public databases in the future: bioinformatics centres need not simply provide data, but are now able to offer the means by which information is visualised and manipulated, without the requirement for users to install software.
To provide a neurophysiological basis for the opponent nature of color vision it has been previously argued that a color cannot be both red and green because color-opponent neurons cannot respond to both red and green at the same time. The present analysis shows that such arguments hinge on the possibility of excluding statements of the kind "a color can be both red and green." For an empirical fact to exclude such statements, these statements would have to be meaningful. However, statements like "a color is both red and green" are not meaningful and are not allowed in our language. Thus, the properties of neurons are not in a position to exclude the possibility of "a color that is both red and green." This means that this attempt to establish a neurophysiological basis for opponent colors is flawed.
