Hi Emma- I seem to be having a different problem with the read.ply function that I'm hoping to get some help with. I've made sure my files are in ASCII format and I have removed texture information, but when I try to import them into geomorph I am getting the following error: *Error in if (sum(normals[1:3, it[j, i]] * normal) < 0) normals[, it[j, : missing value where TRUE/FALSE needed*
The files I'm working with were generated from CT scans rather than via a surface scanner, so I wonder if that has something to do with it? If so, does anyone have any suggestions as to how I might fix this? Thanks, Claire Terhune _________________________________________ Claire E.
