-------- Original Message -------- Subject: Scales Date: Sun, 13 Nov 2011 07:17:02 -0500 From: Axel Wiberg <[email protected]> To: Morphmet list <[email protected]> Hi, I'm a 4th year student at the University of Stirling writing my dissertation and completely new to all this so bear with me. I'm using tpsUtil, tpsDig and finally MorphoJ to measure some features of insect body parts. I'm using several different species and as a consequence photos have to be taken at different magnifications. I'm wondering if it is still possible to make a .tps file of all the body parts I want to measure and change the scale half way through? It also seems like I need to have the same number of landmarks in each picture within the .tps file. Given this how do I set the scale using a separate picture of an object of known length? (It was not possible to include a scale bar in each image.
Hi, maybe you can use some indipendent measure of the body parts that you have in the picture. For example, let's say that you have a wing in the picture, you take a measurement of the same wing under a stereomicroscope and then use this measure to set the scale on tpsDig2... I hope this helps...
