Dear Rachel

You can calculate the interlandmark distances that you want by using
Morpeus et al. following these steps

You insert in morpheus your data as tps (data.tps) and you save it as a
file of morpheus (data.mdt)
Than you open this file with the wordpad and under the command line obj2
you add:

dist"name of distance" landmark 1 space landmark 2


for 5 landmarks in 2D all possible measurements that would be:


dist "AB" 1 2

dist "AC" 1 3

dist "AD" 1 4

dist "AE" 1 5


Than you save the data.mdt file

You open this file with morpheus and you export matrix

than you open the matrix file with excel and you have your measurements


(assuming your original data file had the scale included)


Good Luck

    Hi there,



    I’ve already conducted GM analysis using tps software but I need to go
    back and get basic measurements (length and width). I believe I can use
    the Linear Distance Measurement tool in tpsDig2 but it gives the
    measurements in pixels. How do I convert this to a distance measure –
    either mm or cm?



    OR is there an even easier method? Can I somehow ask the program (or
    another program) to simply calculate the distance between the two most
    extreme landmarks I’ve already added?



    Any help would be much appreciated!

    Cheers

    Rachel
