RE: [MORPHMET] Use of outline tool on TPSDig

2016-10-07 Thread f.james.rohlf
If you set a number of points less than the digitized number of points then the software has to interpolate and that is likely to cut off the corners. This is especially true if the shape is irregular. No easy solution except that you can edit the points and push them around to where you would

[MORPHMET] tps updates

2018-01-30 Thread f.james.rohlf
I have just uploaded ver. 2.05 of tpsSuper, 2.31 of tpsDig2, and 1.75 of tpsUtil. Main change to all three was to add additional image file formats - most importantly camera raw images files. See the list below. This change was suggested by Jennifer Valvo. In addition, I fixed a problem

You can only process one file at a time. If your data are in many files then combine them using the tpsUtil program. F. James Rohlf, Distinguished Professor, Emeritus. Ecology & Evolution Research Professor, Anthropology Stony Brook University

I have just uploaded tpsUtil with a small update - version 1.76. The area/perimeter option can now use .nts files and not just .tps file. It also now includes a PDF file copy of the help file. Some may find that helpful. F. James Rohlf,

RE: [MORPHMET] Digitizing landmarks on live larvae

2018-02-28 Thread f.james.rohlf
Bending of long slender organisms (or other structures) can be an important practical problem. Changes due to bending could dominate the results. Separating sets of landmarks into more rigid sublets can help as long as the endpoints of the subsets are homologous and not arbitrary or dependent

Re: [MORPHMET] Re: Multivariate PICs?

2018-03-29 Thread f.james.rohlf
The thing to remember is that the comparative methods adjust for the lack of independence of the observations. Thus variables being multivariate does not change the computation of PICs or, preferred,  the use of generalized least squares. __F. James Rohlf, Distinguished Prof.

RE: [MORPHMET] PC1 correlation with CS and length

PC1 by definition corresponds to the direction of maximum variance in your data. Within a species and sex this usually corresponds to size and/or age if you include specimens that do vary in size. However, if you include different species and sexes or specimens that are about the same size then

An improved version of this type of correction (the delta-corrected K-S test for an intrinsic null hypothesis) is discussed in the text Biometry (Sokal and Rohlf, 4th ed. 2012) and a table Y is also provided for this test. It should be more widely known and appreciated.

I have uploaded ver. 1.78 of tpsUtil to the http://life.bio.sunysb.edu/morph website. It just fixes an internal exception error when one completes the "unbending" option (after the output file was saved). Thanks to Gabriel Gazzana Barros for reporting the problem.
