Imagemagick worked for me real good. Wnen splitting a tiff file, basically converting from tiff to tiff, one can use a flag to force saving output files to individual tiff files. To do that, try
convert input.tif output-%d.tif
The %d operator is a C-Printf style %d. So, if you need a 3 field running sequence, you can say
convert input.tif output-%3d.tif
and so on.. %d is replaced by "scene" number of the image. Now, scene numbers may or may not always start with 0 (or 1, if you want it that way). To setup a sequence the way you want, try
convert input.tif -scene 1 output-%3d.tif
This would start the sequence right from the count you provided.
convert -scene 1 input.TIF output-%d.TIF output-1.TIF output-2.TIF output-3.TIF
Magick indeed!! :)
