Re: [Gimp-user] image alignment/registration

So, backing up a step: when you say align_image_stack doesn't work, what 
do you mean exactly? I assumed you meant that it did a poor job aligning 
the images, but I don't think the command lines you list there would 
even work to start the program, so I'm wondering now if you meant that 
it doesn't even run?

"-a" requires a prefix following it, and "-g" requires a number.

E.g.:

align_image_stack -a someprefix -g 8 *.tif
