Hi Jan,

Yes, you can easily create a macro using the getHistogram function using 4 bins.
See the documentation and example macros at
    http://rsb.info.nih.gov/ij/developer/macro/functions.html#G
(You must convert the image to a 16 bit or float type first for this to work.)

Subject: measuring intensity quantiles

Dear
all,

is
there
a
quick
way
to
measure
the
90-percent
quantile
of
intensity
within
an
ROI
(instead
of
just
the
Mean,
Min
or
Max)
?

Thanks
for
your
help,
jan
