- As things are going more and more settled, the parameters are not
changing that often anymore as it was at the beginning. So obviously if
you download the new version a few times a week it is unlikely that you
need to change your parameter files the same amount of times, or even once;
- Sometime new options/features come along with the new parameters for
them. I'm wondering how people who download the newer version to use
these options, will actually use them without updating their parameter
files. In this case they just pretend using them -:)
- If we really want to keep "--unused-ok", then we should probably make
it less obvious to use for newbies. If an expert knows it exists (which
will be mentioned in the docs), then great - use it at your own risk.
But for new users it is often the first thing they see when they
mis-format they parameter files.
- One day running phenix.refine will be matter of running one command or
hitting one button with no need to edit any parameters. That will be the
day when the *true* automation of refinement won.
