Re: [MORPHMET] Re: plotting landmarks on Morpheus?

[Emma Sherratt]

For 3D surface models, I suggest IDAV Landmark Editor (
http://graphics.idav.ucdavis.edu/research/EvoMorph) or the commercial
version Checkpoint that Dennis mentioned below. Meshlab's pick points
function works. Also digit.fixed() function in geomorph R package depending
on the specimens.

If you have lots of specimens, IDAV LE has an semiautomated placement
system that is still the best IMO.

[MORPHMET] Re: plotting landmarks on Morpheus?

[dslice]

If you mean Morpheus et al., this program does not do any manual data 
collection. I have tried for years to get a scicomp student interested in 
writing such a module, but to no avail. I have written several digitizing 
programs over the decades - providing graphical feedback and interfacing to 
digitizing hardware, but cannot find the time to do this myself.

I don't need to collect data that often but for 2D data, I use tpsDig by 
Rohlf. For 3D data from meshes, I use Meshlab. That has worked sufficiently 
in the past, but not always as advertised on the Mac. Others have used 
Landmark Editor. I think the old version is free, but unsupported, while 
the new version Stratovan Checkpoint may be a commercial offering - 
https://www.stratovan.com/blog/landmark-editor

Others can chime in with their favorite data collection modality.
