When I run "./3Dreflection logo_screen.gif out.gif" in Windows 7 with Cygwin (I have download the 3Dreflection 3Drotate scripts)

convert: UnrecognizedAlphaChannelType 'extract'.
./3Dreflection: line 328: 3Drotate: command not found
convert: unable to open image './3Dreflect_3_6424.mpc': No such file or directory.
convert: missing an image filename 'out.gif'

The ImageMagick version is 6.4.0.

Why did it happen?

you probably need a more current version of IM. IM is at 6.6.7.0, so you are about 270 versions behind. -alpha extract was a relatively new feature, but I don't know exactly when it was added. you could check the changelog at http://www.imagemagick.org/script/changelog.php
