[MORPHMET] WarpRefMesh p x k matrix read problems.

[ashleigh.haruda]

Hello all, 

I am stuck on what is probably a very easy issue but my normal sources for 
troubleshooting just haven't been very helpful lately. 

I'm trying to visualize any kind of warps on a 3D .ply file. In the past, I 
used a combination of MorphoJ and Landmark (IDAV) but the quality of the 
images wasn't very good, so I'm attempting to use Geomorph in R to make 
better quality visualizations. 

I have managed to import a .ply file for the most 'average' shaped 
specimens and .dta files created in Landmark into Geomorph with no issues, 
however whenever I attempt to execute WarpRefMesh (say, to make an average 
reference mesh or for shape variation along PCs), I get this error: 

Error in warpRefMesh(OriginScan, Cer19Coords, meanshape) : 
  Input must be a p-x-k matrix of landmark coordinates

I've attempted to sort this error out in a number of ways- I have checked 
the dimensionality of each landmark matrix (Cer19Coords, meanshape), 
ensured they are matrices, and even discarded my original .dta files to 
attempt to re-landmark my OriginScan in Geomorph- all to no luck. I 
continue to get this error even when I attempt to warp along PCs. 

Any suggestions on how I can get this work? I feel that I am missing 
something basic here, but have been backwards and forwards through the 
Geomorph manual for a couple of weeks now to no avail. 

Thanks, 

Ashleigh

[MORPHMET] Open Access Repositories for GMM data and 3D models

[ashleigh.haruda]

Dear All, 

I've been investigating open access repositories to deposit both 3D models 
as well as GMM data and have been struggling to find any which offer 
built-in support and pricing for these types of data. I work mainly with 
zooarchaeological specimens, so I am most familiar with archaeological 
repositories such as Open Context and ADS. Does anyone have any other 
suggestions for good open access sites? I'm particularly interested in 
those which already have support in place, without having to create 
customized plans for acquisition and pricing. 

Cheers, 

Ashleigh
