JPEG decompression error

[carlosmanacorda]

Hello everybody,

I am just trying to use geomorph to digitize my data for subsequent analysis. In a separate folder I have placed 13 photographs and created a .csv file with the names of each image (IMG_5859, IMG_5869 and so on) in a column. Then I wrote:

digitize2d("filelistColDL2.csv", nlandmarks=6, scale = NULL, tpsfile= "tpsoutputColDL2.tps", MultScale = FALSE, verbose = TRUE)

And the outcome:

Digitizing specimen 1 in filelist
Error in readJPEG(filelist[i], native = T) :
JPEG decompression error: Not a JPEG file: starts with 0x49 0x4d

However, when I inspect the Properties of the images, they are said to be "Image JPEG (.JPG)".

So, were is the problem? And is there a way to fix it?

Many thanks in advance!

Carlos, You first need to read the csv file into R, and then give that list to digitize2d. Dean Sent from my Verizon, Samsung Galaxy smartphone
