Hello All, I am having trouble with the gpagen module in Adam et al.'s Gemorph package, and I am hoping someone here may have encountered the same problem or have some insight into my problem.I am applying gpagen to execute GPA with sliding surface semilandmarks (bending energy criterion). I am running the most recent versions of both R and Geomorph.
According to the documentation, gpagen should return a list comprising 1) $coords: the aligned coordinate matrix and 2) $Csize: a vector of centroid sizes. Instead, it is returning aligned, slid configurations in the same 3D array format (p, k, n) as the infile (generated using readland.nts) but no centroid size vector. I have compared the pre- and post-slide configurations to confirm that sliding is occurring. I have tried running the csize module separately and gotten similar unsatisfactory results. Can anyone explain why I am getting partial output or recommend a fix or workaround?
