James Rohlf <[email protected]> Reply-To: <[email protected]> Organization: Stony Brook University To: <[email protected]> References: <[email protected]> To obtain a file that you can import into Excel, it is best to use tpsUtil to convert the NTS file to a .CSV file that Excel can read directly. Use the "Convert tps/nts file" operation and then select file type *.CSV for the output file. There will be no line wrapping if you do this. ========================= F.

I have samples from two different populations (lakes) of these color forms and can also subdivide each color form by sex. I used tpsRelw to generate and save a weight matrix containing the partial warps and uniform component shape data. The "report" generated from tpsRelw indicates there are 30 relative warps. When I attempt to transform the nts weight matrix data into excel (using Delimited: tab and space) only 5 x,y data pairs appear in columns. Also, the number of rows representing specimins is equal to 723 which is 3x my number of specimens. Should I not expect to have one row per specimen with 30 x,y data pairs (representing the 30 relative warps) plus one x,y pair representing the uniform component? Is there a data wrapping function that would explain this format? I have used tpsUtil to "build a variable matrix" and I hope to combine my variables (lake, color, sex) with the weight matrix and use tpsRegr to examine the effect of these variables. Does this sound like the best approach for this type of data? Any advice would be greatly appreciated! Thanks! Mark H. Schmitz PhD Candidate UW-Milwaukee -- Replies will be sent to the list.
