Hello, I used a commend that I often use to merge PNGs in r.

efa.p1 = image_read("C:/Users/teind/Dropbox/ניתוח עבודות/עטרת גבירץ מדיני 20-5-2015/p11/Study 1/PA.png") efa.p2 = image_read("C:/Users/teind/Dropbox/ניתוח עבודות/עטרת גבירץ מדיני 20-5-2015/p11/Study 1/CD.png") efa.p3 = image_read("C:/Users/teind/Dropbox/ניתוח עבודות/עטרת גבירץ מדיני 20-5-2015/p11/Study 1/MAP.png") magick::image_append(c(efa.p1, efa.p2, efa.p3))

and I got the following error: Error in magick_image_join(x) : external pointer is not valid I have included the files.

Do you run this in a regular R session? Usually you get the external pointer is not valid error if you restart R after loading the images, or somehow try to run this in a way that tries to cache the images to disk.

It has nothing to do with the images itself.
