Hi Paul, could you please comment on the precedence of the default settings in either ".coot-preferences/coot-preferences.scm" or its python equivalent. The comments in the file state that the user should feel free to edit the values, but not add/delete entries. This could potentially lead to a situation in which only the .py or .scm file is modified and the defaults are not applied, since they get overwritten by the other defaults file. The same argument could apply to a .coot and .coot.py file. Which one has precedence? Are there any plans to streamline this into one single scripting language?

Coot does not create a ~/.coot file for you, but will read it if it exists. Likewise, ~/.coot.py in which you can write python commands. ~/.coot-preferences is a directory in which all .scm files and .py files are executed. coot-preferences.scm and coot_preferences.py there are generated by using the Edit -> Preferences dialog (and thus it overwrites older versions - hence the warning). If you want to create a script that will be read by everyone then put those files into a directory define by environment variable $COOT_SCHEME_EXTRAS_DIR (for *.scm) or $COOT_PYTHON_EXTRAS_DIR (*.py). All *.scm in $COOT_SCHEME_EXTRAS_DIR and *.py files in $COOT_PYTHON_EXTRAS_DIR will be executed at start up. So you have a variety of places. Personally I mostly use ~/.coot. Paul.
