re: Chimera 1.1951 on OSX 10.3.4 fails to do much at all... I'm a first time user obviously! :-) Trying to open Side View or any of the Tools:Viewing Preferences fails. Many commands via the command interface likewise fail, e.g. surface #0 (no module msms), (no module webrowser). AFAICS from the error messages, the errors appear to be either Python modules missing or Tcl/TK errors. My download is the correct size. Q: Does Chimera require a Tcl/TK installation? - which doesn't show these up and they aren't hidden in one of the sbin's (I'm assuming that they are named tcl and tk - I've never had to work with them directly myself). If so is this tested on start up? There appears to be nothing about this in the docs AFAICS. The OSX installation instructions only say to drag the app. to the disk, nothing about other requirements. So naturally that's all I've done so far! If it does require more stuff, would someone be so kind as to tell me exactly what and where to get it? Two suggestions: It'd be good to have a simple test of what modules are present to "verify" an installation. (e.g. Tools:test:modules) It'd be good to have a test of the presence of Tcl/TK & let the user know it its not around.
