Hi Gabi,

You need to create a tab delimited text file in which you will have three columns. The first column starts with zero and is followed by the coordinates of the first landmark. The rest of rows in this first column will still be zero followed by the coordinates of the rest of your landmarks until you get to the first line (all coordinates are then numbered zero in the first column). Then you will name each line by putting the number in the first column corresponding to the first line and then continue to type the x y coordinates for the coordinates that make that line. Thus, after having named the first rows as zero and typed the coordinates for them, you will number as 1 all rows that make up the outline of the structure with the xy coordinates. To generate the coordinates, you can create a dummy file in tps.dig that contains a specimen of yours with landmarks and create and outline file that you can save as xy  coordinates. If your specimens are too variable in shape, perhaps you might construct two outline files and use the most similar to the extreme when your trying to plot extremes in Morphoj.
The text file will look like this if you have three landmarks and two lines (xy coordinates made up for the example):
0       345      678
0       567      564
0       875      123
1       345      678
1      456       567
1.....
1.....
2       321      687
2       456      983
2.......
2.......      

I might be wrong at least as to if this is the most efficient way to do it but it works well! I am pretty sure the text file format is in the MorphoJ manual.
