[MORPHMET] Re: Appending tps curves to landmarks
UPDATE: The problem was that I was working with an older version of tpsUtil, I think. Or possibly an error in the original download. After re-downloading the software to the newer version my files now open without error.

[MORPHMET] Appending tps curves to landmarks
Hi All I'm currently trying to append curves to landmarks using the function in tpsUtil (I want to use the curve information as sliding landmarks) however any time I try to do this tpsUtil gives me an error message saying '0.004149' is not a valid floating point value.' I take this to mean that one of the points I made when digitizing is not "valid" and so tpsUtil cannot read the file? Is this right? When I was digitizing tpsDIG kept popping up error messages but I couldn't figure out what I was doing wrong, I was just tracing the outline using the 'draw curve' function. I'd delete the curve and start over, but it happened every time I outlined a molar so eventually I jut kept going. Did this mess me up? Was there a way to fix what I was doing that would have meant my curves would be read in tpsUtil? Is there a way I can manually append my curve data as landmarks that could still be read into Geomorph or Momocs as sliding landmarks? Could I edit the tps file manally to do this or am I going to have to start over redrawing the curves? I need to delete some landmarks as well, so I'm having the same problem with tpsUtil, I was planning on manually deleting the landmarks I no longer want for my specimens (or should I just tell the R packages I use to exclude certain landmarks? I think this might be better).

Re: [MORPHMET] Landmarks coming up funny in MorphoJ
Hi Guido Thanks so much for the suggestion, I'll definitely do that. Is there a particular way to save a wordpad/notepad file as a .tps format file? I've tried to do this before but it kept saving as a .txt file, or would this still work?

[MORPHMET] Landmarks coming up funny in MorphoJ
Hi All, I'm trying to analyze measurement error in MorphoJ but I'm running into a problem. When I digitized my landmarks I used tpsDIG2, however I had to organize those coordinates into a CSV. file because I digitized them in two separate .tps files and tpsUtil wouldn't allow me to open the one that required I delete some specimens I didn't landmark (I thus couldn't join the two files for analysis). So I collated them in a CSV. However, when I look at the outliers in MorphoJ the landmarks come out in a horizontal line instead of in the shape of a mandible. I can't analyze this. It doesn't seem to take the x,y-coordinate as coordinate pairs, from what I can see it places 26 landmarks in a horizontal line, instead of the 13 pairs I digitized.
