Sorry to hear that. Anyway thank you for trying, I guess I'll have to
fix them manually.
Regards,
Víctor.

Dear David and lilyponders:
I'm glad to see that you are around here again, so now I
hope it will be not much of a trouble if ask you to take a
look to the aforementioned problem with the ties and centered
notes. For those who don't know what I'm talking about, David
Nalesnik programed a very useful function that centers notes
when they occupy the whole measure. The problem seems to be
that tie's length is not recalculated after the note column
has been moved; and since my scheme-fu is very basic, I just
can't fix this myself.
I'm sorry, but I don't know how to fix this.
The problem lies in the code for determining whether the
PaperColumn to center or ignore is alone in the measure. This
requires access to other columns in the line, and these are
located through the grob-array 'columns. Unfortunately, this
array is empty until line breaking has occurred. By then, it's
too late to do anything about the ties, as far as I know. If
there were a way to get the previous and adjoining columns before
line breaking, that could possibly fix your problem. I don't see
a way in Scheme, but I'd welcome being wrong about that.
And you might think 'left-neighbor and 'right-neighbor
(http://lilypond.org/doc/v2.19/Documentation/internals/spaceable_002dgrob_002dinterface)
would be exactly what we want. Works for an override of
PaperColumn.after-line-breaking but we come up empty for
'before-line-breaking:
\version "2.19.25"
{
\override Score.PaperColumn.before-line-breaking =
#(lambda (grob)
(let ((left (ly:grob-object grob 'left-neighbor))
(right (ly:grob-object grob 'right-neighbor)))
(format #t "left neighbor: ~a right neighbor: ~a~%" left right)))
c'1
c'1
}
