[MORPHMET] How to include new specimens in TPSdig and information on EDMA software
Dear morphometricians I have a couple of quite simple questions 1) Once one has digitized a set on landmarks/semilandmarks in a series of photographs it is possible to include new specimens?. I mean, if I have a digitized dataset and I want to include new specimens it is possible?. I tried but I only found the way to exclude specimens/individuals and/or landmarks in TPSdig2 and TPSutil. 2) I want to know if there exists a new version of EDMA software. I want to run analyses in EDMA but in PCs with updated versions of windows (7 and 8) the old version of WindEDMA may present some incompatibilities. thanks in advance cheers Miguel -- MORPHMET may be accessed via its webpage at http://www.morphometrics.org To unsubscribe from this group and stop receiving emails from it, send an email to morphmet+unsubscr...@morphometrics.org.
[MORPHMET] Method to digitize 3D semilandmarks using microscribe
Dear all Happy 2016!! I am conducting a geometric morphometric research to evaluate the cranial and mandibular shape variation in a sample of modern humans. I am using a microscribe digitizer. I would like to describe as best as possible the shape variation so I am interested in 3D semilandmarks. So I want to know if somebody have used a semi or automated method to digitize 3D semilandmarks using a microscribe. Maddux and Franciscus 2009 J Hum Evol 56 161-174 describe a quite interesting method using a LCD projector and a grid, however such method does not allow to digitize optimally the semilandmarks along a curvature for instance the middle line of the cranial vault from a lateral view or the complete vault in the same view. So if any may share his/her own method I would be very gratefull.

Re: [MORPHMET] Mahalanobis distance in cluster analysis of shape variables
Usually researchers use small sample sizes for distinct reasons in my case because I study archaeological and paleontological derived samples. The practical problem mentioned by James could be partially solved correcting the D2 distances for small sample size, that is, calculating an unbiased Mahalanobis distance ∆2 following Marcus L. 1993.

[MORPHMET] Software to join multiple slices derived from Computer Tomography
Dear All I recently obtained several CT scans from hominin crania. I used 3DSlicer 4.5 to robtain 3d meshes of such crania. However I noted that in my database there are two kinds fo files. One of them have a .hdr extension which can be succesfully loaded into 3DSlicer which alllowed to obtain 3D meshes. The other type of file contains multiple slices (with extension .DCM) which when they were loaded individually in 3DSlicer did not allowed to reconstruct the 3D model. It may be necessary to edit (i.e.join) slices before I can load into 3DSlicer, Someone knows what procedure should I use to join the slices? Any suggestions of some software or tips on how to get the 3D model from those slices? Thanks in advance Miguel * Miguel Delgado PhD CONICET-División Antropología.

Dear Ariadne and Thomas Thank you so much for your suggestions.

Re: [MORPHMET] Script to read Avizo landmarks and B-splines
Dear Murat and Antonio,
Thanks for your fast response. Of course Murat here I attach the
corresponding files (they derived from Avizo not from Amira)
Antonio yes I tried to use the Arothron function read.amira.set () but the
following error appeared: argument "nland" is missing, with no default.
Here I attach three files one is Landmarks_LLM1_landmarksAscii (landmarks
from a human lower molar) and one B-spline in Avizo binary (*.am) format
and the same file in Avizo ascii (*.am) format
(zan0084_manleft_mirrored_01_curve_LM1.am and
zan0084_manleft_mirrored_01_curveascii_LM1.am)
Thanks for your help
