To follow up on Michelle's comment, Morpheus recognizes 9999 as missing
data, so my template always starts off with all 9999 (for x, y, and z).
I would then simply digitize actual data over each column in Excel. 9999
is also an "outrageous coordinate," so it is very easy to catch in your
dataset.
That's during digitization... but, trying to locate missing data during
analysis for every single specimen is a whole different level of PAIN. I
use SAS, but it's quite complicated (requires knowledge of SAS
programming). So I am interested in what others have to say on this issue.

Hi Tom,
Most of the TPS programs do not support missing data. I've only used
TPSDig once, and my recollection is that we placed missing landmarks
in the "corner" of the window, giving them outrageous coordinates
that were easy to identify in the data files, then replaced them
manually with missing data signifiers for statistical and
morphometrics analysis in more forgiving programs. Last time I
checked, Morpheus and Landmark Editor support missing data;
Morphologika and the aforementioned TPS programs do not. Those more
familiar with other programs care to chime in?
Cheers,
Michelle

Is there a way to identify missing landmarks when using TPSDig?
How about some of the other programs?
Thanks
