When working with registered and aligned images that are of different size, I use imagemagick to frame the 16 bit tiff files, with this little script:
#!/bin/bash OUTPUTRES="4300x2900" mkdir output for filename in *.TIF*; do convert "$filename" -background black -gravity center -extent $OUTPUTRES output/"$filename".out.tif done for filename in *.tif*; do convert "$filename" -background black -gravity center -extent $OUTPUTRES output/"$filename".out.tif done
