Not quite the way I intended the tps software to be used. The “curves” feature was originally intended for curves to be shown but not actually used in any computations. Some now do use it to enter points intended to be semilandmarks – perhaps because the lines connecting them give the impression of belonging to cures. Appending tps curves to landmarks feature can be used but it is an extra complication.
In tpsRelw only landmark points are used. If the sliders file is input then the indicated landmarks will be used as sliding semilandmarks. Note: unless a curve is very complex, 40 semilandmarks to probably too many. The tpsUtil program should not, of course, crash. Please provide me more details about the version used, the input file, and at what point the program crashed. I will then try to fix the problem. ____________________________________________ F.

What I have done: 1) digitized normal LM (13) 2) created a curvature in tpsDig and resampled curve by length with the same number of LM (40) for each specimen 3) with tpsUtil “Append tps Curve to landmarks”, I transformed 40 curve points into LM. At this point, the file looks fine: LM=53 (13 real LM + 40 come from the curve points). I can also open it in MorphoJ but I all 53 points are shown as LM, not semiLM. However, when I use this file in tpsUtil to "Make sliders file", I get an error: "Access violation at address "00449136 in module "tpsUtil.exe". Read of address 00000008." I click several times OK and get a window with "No semilandmarks" I get 3 options: "Load Semi.", "Create", and "Cancel". If I click "Create", an .NTS file is created but it's not possible to open it with MorphoJ. MorphoJ gives as error "The chosen dimentionality and the number of data columns in the file are inconsistent". Could you please explain me what I do wrong? I will appreciate any help and/or suggestions.
