Also the software is not being updated with the changing Windows operating systems, so it still performs the best on XP machines. I have tried withВ minimalВ success to get it working on a virtual machine, because it has high-reliance on the VRAMВ and RAM,В particularlyВ with large meshes. PLY files, and has a nice feature of setting correspondence between meshes for semi-automatic digitizing. Landmark Editor by IDAV was theВ softwareВ I used the most before starting with geomorph.

Videos demonstrating how to use these are here. Semilandmark data can also be collected with geomorph, using either digit.fixed(), or buildtemplate() and digitsurface(). As mentioned already, the benefit of using geomorphВ and RВ is that it worksВ on Mac, Windows and Linux. NTS file, which canВ be read into geomorph (using readmulti.nts() ). The landmark data for each specimen are written to a. These already contain the scale of the specimen, so all one needs to do is place the landmarks. , which are one type of 3DВ surfaceВ file ( Meshlab is great freeВ softwareВ to convert files intoВ this format). GeomorphвЂs function digit.fixed() allows users to digitize 3D landmarks on surfaces of. Related to ImageJ is FiJi, developed for more image processing. Advanced users can even make their own macros in ImageJ for their specific needs. For importing into geomorph, itвЂ™s best to save it as one row per specimen and x1,y1,x2,y2 вЂ¦ columns, then it can beВ broughtВ in using read.table() and converted to a 3D array using arrayspecs(). The coordinates are printed in the results window, and need to be copied into an excel sheet (or your freeware equivalent) and saved as a text file. Then you can use the point tool to click and place landmarks. But it is simple: Import an image measure the scale using the line tool and cmd+M, the go to Analyze > Set scale and set what the distance in pixels is in mm. It isnвЂ™t specifically for 2D landmark data, so it can be daunting to start with becauseВ thereВ are so many other features. ImageJ from NIH is the go-to image manipulation and measurement tool, a must for any morphometrician.

TpsDIG is onlyВ availableВ forВ Windows, but is not too RAM-demanding so can be run on Virtual machines (a good free virtual machine is VirtualBox). The GUI interface is veryВ user-friendly, and it facilitates collecting both landmark data and also curves and outlines. A good video tutorial of how to use this software is found here. TpsDIG distributedВ by F.James Rohlf on the SUNY Morphometrics website, is the classic 2D landmark data software. One benefit of using geomorph and R is that it worksВ on Mac, Windows and Linux. TPS file of the coordinate data, which canВ then be easily read into geomorph (using readland.tps() ).

jpeg file after the next, set the scale and place the landmarks. GeomorphвЂs function digitize2d() allows users to read in one. But many people for good reasons prefer more GUI-based applications for their dataВ collection, and so I will present a brief overview of some common and easy to find options. Geomorph is, of course, free, and available on CRAN, which is also free! I will be highlighting several geomorph features here. And the good news is Morphometrics is more free than ever! MostВ importantly though, IВ believeВ in Science being accessible andВ affordable. вЂњДЄnd this is my stance also вЂ“ I spent a good portion at the start of my PhD trying to find adequate ways of getting 3D landmark data from my CT scans of caecilian skulls for free, because I didnвЂ™t want to be tied to the CT facilities computers. And it means that when I train students in the software I use, they can take those skills wherever they go and not have to re-learn a different proprietary package to do something they have already been doing for weeks/months/years. It means grant money can be spent on hardware and materials, rather than software licenses. вЂњusing freely available software where possible means that my skills are transferrable to different workplaces. However, sometimesВ theВ cost of theВ softwareВ is so high it makes it completely inaccessible вЂ“ and software thatВ isnвЂ™t used is not helpful for anyone.

SoftwareВ developmentВ isВ hard work, so it is understandable that it costs money. I though iвЂ™d write a complementary piece on free software for collecting landmark-based morphometric data. Peter FalkinghamвЂ™s blog postВ on freeВ softwareВ choices for working with 3D slice data and surface models (acquired by micro-CT, laser/photo surface scanners orВ Photogrammetry). I have seen a few questions floating around the interwebs recently from people starting up in morphometrics and wondering what is the best software to use.
