First, the morpheus et al. download problem resulting from file
shuffling necessitated by the life.bio crash some time ago has been
fixed. I will contact individuals who have asked about this individually
later.
Second, I have been asked to remind folks of how to compute measurements
in morpheus. The information from the help files and the help index web
page is given below.
The way I use this capability is to create a morpheus file with the
required measurements (just a test file with the measurement commands as
described below), load in a data file, then, append the measurement
file. In this way, measurement commands are kept separate from the data
and can be used with different data files.
Values of measurements can be listed (list measurments) or exported
along with the other data to various formats.

***********************************************
Measurements
Measurement data types are specifications of measurements to be
obtained from curves or sets of points belonging to individual
objects. These variables are considered global and the
measurements are taken from every object for which appropriate
data are available. The general format of a measurement variable
is:
'type' "label" i, j,,
where 'type' is 'DIST', 'ANGL', 'ARCL', 'PERI', or 'AREA', for
distance, angle, arclength, peri meter, and area, respectively.
"label" is a quote delimited label that is required, but may be
empty, e.g., "". The remaining integers indicate the specific
data elements to be used for the measurement. Their number and
meaning depend upon the measurement being defined. Some examples
are:
DIST "length" 1 8
ANGL "" 1 4 8
ARCL "dorsal fin arc length" 4
PERI "body perimeter" 1
AREA "pupil area" 2
In these cases, the distance is measured between points 1 and 8,
the angle between points 1, 4, and 8, and the arclength,
perimeter, and area are computed for curves 4, 1, and 2,
respectively. Note, PERI assumes the curve is closed, ARCL does
not. The values of angular measurements are reported in units as
determined by the 'degrees' or 'radians' program variables.
