[MINC-users] Power spectrum across time

[vladimir.fonov at gmail.com]

Hello,

I extracted the tool from my internal repository, see https://github.com/vfonov/simple_fmri_tools 
the tool that you need is called time_fft  ( https://github.com/vfonov/simple_fmri_tools/blob/master/src/time_fft.cpp ) - it will only work if the time_dimension is fastest varying.
