Morphomet community, I have head shapes from specimens that were digitized multiple times to reduce measurement error. My goal is to use average head shape of specimens for downstream comparative methods (where each specimen represents a different lineage). Just want to be sure I am doing GPA on the appropriate unit. Here are some different ways I have thought about doing GPA on the head shapes for my specimens:
1. All coordinates combined (i.e. replicate measurements across specimens) 2. On a specimen by specimen basis 3. By specimen's average unaligned coordinates OR 4. GPA twice, on specimen by specimen basis (like #2) and then by specimen's average aligned coordinates Which approach seems most logical? n -- MORPHMET may be accessed via its webpage at http://www.morphometrics.org --- You received this message because you are subscribed to the Google Groups "MORPHMET" group.
