I wanted to mention that after posting on the ImageMagick discussion board on github, I learnt that the restriction does not hold for converting to PNG (but for JPG) so I was able to convert it. However, I am not able to read the file into R (even with 0.5TB RAM) so I will unfortunately have to look at other options than R:-( I think I will write the code in C, but the PNG gives me a better start than I would have had with the original file.
ImageMagick can do cropping of files, so if the R limitation is due to size, you could break up the file before trying to read it.
