Hi Pablo,
A small change should fix it. Remove the “prefix” argument. Whatever you set
“prefix” to is pasted in front of each specimen name. Notice how the error says
there is no such file "E:/Documents/hominoid/A860ho, USNM083262hy,
USNM084655pan, USNM143590po, USNM143593po, USNM174699pan, USNM174701pan,
USNM174702pan, USNM239883go, USNM260582goA860ho.landmarkAscii.ply”.
This is your path ("E:/Documents/hominoid/“), then your “prefix”, then the name
of the first specimen in “data”, which is “A860ho.landmarkAscii”, then the file
extension, “.ply".
Try it like this:
dimnames(data)[[3]]=str_remove(dimnames(data)[[3]],".landmarkAscii”)
patched.specimens <-
placePatch(atlas=atlas,dat.array=data,path="E:/Documents/hominoid",prefix ='',
fileext=".ply"))
If the dimnames(data)[[3]] perfectly match the filenames of your ply files
(without the “.ply”), it should work.
Best
