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?

Many, many thanks,

Michelle Singleton
