[MORPHMET] Using photographs from distinct sources to GM analyses

2016-03-12 Thread Pablo Fisichella
Dear Morphometricians I am new in geometric morphometrics. I have a question perhaps quite simple with regards to 2D GM. I am comparing the size/shape of human skulls from different sources using photographs taken in norma lateralis. One part was obtained through a standardized protocol while the

[MORPHMET] Dating morphological divergence

2016-07-01 Thread Pablo Fisichella
Dear all I have an inquiry perhaps trivial!!. I want to know if there exist a technique/method to date evolutionary divergence using morphometric or geometric morphometric data in a similar way that the divergence dating using molecular variants. For example, using evolutionary rates to obtain

[MORPHMET] Question on combining 3D data from microscribe and CT models

2016-08-24 Thread Pablo Fisichella
Dear morphometricians, Currently I am performing a study on 3D human craniofacial morphology. I have data derived from microscribe and from 3D models obtained from CT scans and procesed in landmark Editor software. My question is if it is possible to combine both kinds of 3D data within the same

[MORPHMET] Question on combine datasets in MorphoJ

2017-08-13 Thread Pablo Fisichella
Dear All I am analyzing 3D coordinates from non-human primate molars. I have in the same dataset coordinate data for M1, M2 y M3. I performed multivariate analysis using the size and shape (form) of all teeth together (M1, M2 and M3). Now I am interested in perform analysis comparing individual

Dear All I am using the package Morpho in order to make some GM analyses but I obtained some errors. Now I am trying to use the function read.csv.folder I ran this command a<-read.csv.folder("E:/Documents/Zan2", x = 2:44, y = 2:4, rownames = NULL, header = TRUE, dec = ",", sep = ";", pattern =

[MORPHMET] How to obtain measurements from 3D scans

2018-09-09 Thread Pablo Fisichella
Dear morphometricians I am interested to obtain linear measurements from 3D models of human fossil teeth. Given that I don’t have more access to the fossils now I am planning to use the 3D length tool in Avizo to obtain the measurements that I need. My question is if the measurements obtained

[MORPHMET] Help with surface scans

2019-04-22 Thread Pablo Fisichella
Dear All I´m trying to obtain surface scans from human skulls and lithic artifacts (projectile points). I wonder how can I get the most complete possible scans, I mean usually is not possibly to obtain a complete scan at once. I know that several post-scan processing software have functions to
