Hi Andrea,

you can also check out ImgLib2: http://fiji.sc/ImgLib2_Examples#Example_6c_-_Complex_numbers_and_Fourier_transforms <http://fiji.sc/ImgLib2_Examples#Example_6c_-_Complex_numbers_and_Fourier_transforms>

It is part of Fiji and can be called through a Beanshell script for example.

Hope this helps,
Stephan
