Date: Thu, 11 Jun 2009 07:29:54 -0700 (PDT) From: andrea cardini <[email protected]> To: [email protected] Dear Roberto, this is from TPSRelw glossary: The parameter a described by Rohlf (1993) . A value of 0 gives equal weights to partial warps at all spatial scales and is used by default. A value greater than 0 (e. g., 1) gives greater emphasis to variation at larger spatial scales and a negative value (e. g., -1) emphasizes small scale differences. All biological studies I know except a small part of one simply leave alpha as it is (i.e., zero). Cheers Andrea At 09:52 11/06/2009 -0400, you wrote:

I have a question that prevents me from advancing in my analysis of geometric morphometric of populations chilean silversides. When working Relw Tps ... What is the meaning of the values of alpha? That means 0 or 1?. I'm new in this world of GM and I hope to write my first paper in this analysis.
