You have to put in the scale on the pictures. You can do that in the
image tools in the tpsdig. Then the distances should be in the required
distance.

    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
