Using TPS Series of Prof. James Rohlf for resolving problems related to morphology is a common technique in academia. I already used this series in previous successful works, however I do not remember how we can produce NTS files for Thin Plate Spline analysis. I appreciate any help from experts.
Dear Ashraf,
maybe this site that is being updated by prof. James Rohlf can be helpful - http://www.sbmorphometrics.org/soft-utility.html
The first program "tpsUtil" can convert .TPS files to NTS.
Thanks Martin for your help, however I could not convert the file by using this program. May be something is missing in my procedure.
Is there a certain point in the procedure where you are getting stuck? Or maybe an error message ?
I know you may have already tried these, but they were helpful to me when I got stuck with a similar problem -

You do not say what kind of file you have and are trying to convert to an NTSys file. If you have a *.tps file (with each specimen's coordinates in two columns, the LM= (number of landmark) as the first line in each specimen's data, you can save that as an *.nts file. Also, there is a function in tpsUtil that converts *.tps files to *.nts files. If you have some other kind of file, please say what kind of file you have because otherwise it is difficult to suggest how to convert that to an *.nts file.
Thanks Martin and Mariam for your responds. Actually, I could not convert *.tps file to *.nts file by using tpsUtil.
Do you have the most recent version of tpsUtil? I just converted one of my files using it.
Yes of course. Anyway, I may try it again. Thanks so much for your help.
Dear Mariam, my tpsUtil version is 1.81 64 bits. Is it the most recent version? Any information is acknowledged.
That is the version that I have. It has the operation convert tps/nts coordinates files and when I tried it, it worked.
Yes, indeed, I could convert the file. Many thanks, Miriam for your kind help. I appreciate your effort.
The Checkpoint software enables you to collect 3D landmark points and can also export to the format used by Jim's software.

If you are upgrading your digitizing software, you can also upgrade your software for the analyses. Any program that can do analyses of shape can read the tps (or nts) file format, so you can use Checkpoint for digitizing and import those files into any program for geometric morphometrics (like the R package geomorph).
