Dear Paul,
thanks for your comprehensive response in spite of my rather general comment.
And thanks for listening! I hope you see this as constructive criticism and not
only as blunt complaining (a national tradition ;) ):
Instead of a screencast I'd like to give at least a few more details on the
trouble on my end.
The problems mainly arise when:
- switching maps e.g. from 2Fo-Fc to Fo-Fc, or omit maps (X-ray restraints ?)
- modelling alternative / low occupancy conformations
- modelling covalent ligand complexes (atom clashes ?)
- parts of the solution are in either of the maps (maybe map averaging would
help?)
--> which is practically all I am doing, and the result is often a model next
to but not inside of the density. I am a long-term practitioner of ctrl-drag,
but with little help in these cases.
With respect to sophisticated solution and the "method developers’ intention",
I would like to answer with some experience from our own serial crystallography
method development.
For even distribution of micro-crystal slurries, we developed a
custom-multichannel pipette adapter, went through different iterations, adapted
and improved the design added more features optimized parameters and it now
works nicely as intended. However, users rather like to use a single empty
pipette-tip and distribute a big puddle of slurry manually. Not half as pretty
as the solution I intended, but admittedly easier, faster cheaper. Thus, in the
end the user-perspective won over my intention.
With respect to pull-atoms restraints, I don't think more visibility is going
to help the case. The restraints themselves appear to be off (if that’s a
statement that helps in any way).
I hope this helps a little bit to narrow down the hard-to-describe problem.
Best,
Eike

Thank you for your explanation. I will try to adapt my way of working to
the new coot.

Dear Frustrated Coot 0.9 Users,
I'd like to let you know that you I have heard similar reports in the
recent past (including, as you can see, from EJD). I have taken what I believe
to be remedial action to address the most pressing issue.
I think the situation has arisen because Coot users are bringing previous
experience of using RSR into their use of 0.9. Because the movement of the
non-dragged atoms in 0.8.x was rather unsophisticated, many people learnt (I
discovered, rather late in the day) to "flick" the dragged atom with a large
and fast movement to get over a local energy barrier. (Needless to say, I
hadn't intended for that to happen, the approved way to make such modifications
was Ctrl-drag over-dragging.) Applying a large and fast flick to the dragged
atom in
0.9 often leads to an undesired result. If one then misses that fact that
an atom pull restraint is still in effect and goes on to drag on another atom,
then confusion and frustration ensues.
For myself, by using eigen-flip and jiggle fit beforehand and then by
combining pepflip, JED Flip and backrub rotamer during RSR I often don't even
need to pull on the atoms. By adding in interactive contact dots, I can see
what it is that's causing Coot to not move the atom to where I'm trying to drag
it (the NBCs have been re-paramaterized and up-weighted in the 0.9.x rewrite).
I have, from time to time in the past year, used Coot 0.8.x and to me it now
feels painfully crippled. RSR in Coot 0.9.x is joyfully expeditious and
pleasingly animated.
For now (which is to say, before Coot 0.9.1 is available) I suggest keeping
an eye out for unsatisfied atom pull restraints, and using the "Clear Pull
Restraints" at moments of confusion. Also, use less flick and more smoothness
when dragging atoms. For example, a 180 degree rotation of the ribose from the
Coot tutorial would be difficult, if not impossible using 0.8.x, but in 0.9.x
one can pull on the hydrogen atom of the O5'
to rotate it in a few seconds. I have added a (rather poor) video of me
doing just that to my channel (I should make a better video).
With all that said, I am still listening - I will add a change shortly that
will make the pull atom restraints more obvious by making them fatter, pinker
and more opaque. If there are still problems and you could somehow make a
screencast available to me that illustrates the problem, then I would be very
interested to view it.
Regards,
Paul.
