Vector-GMA: A New Easy Method for Analyzing Morphometric Data

Abstract The new method of geometric morphometric analysis, called Vector-GMA is proposed. Unlike the classic TPS-based GMA, the new method allows considering missing and inapplicable landmarks and analyzing articulated structures. It also contains a set of tools for analyzing particular morphological features and searching for promising identification characters. The results of the analysis can be easily converted into phylogenetic matrix and analyzed with phylogenetic software. For the case study, the fore wings of all Cretaceous ichneumonids are analyzed.
