`Version: ImageMagick 7.1.1-38 Q16-HDRI x86_64 22398` convert is depricated; magick is to be used instead. `magick -coalesce file.gif out.bmp` `magick: no images found for operation '-coalesce'` `magick file.gif -coalesce out.bmp` In case anyone, like myself, gets stuck with trying to figure that out.
