I used two 3D input images to do a FAST segmentation with two classes
(CSF and brain matter). The input images were 1) a T2-image after BET
and 2) an ADC-map with the same BET mask. This is the input:
mfast -s 2 -c 2 -os -od adc_t2 t2.hdr adc.hdr
The resulting error is:
Empty input image. Nothing to do!
even though the images were definitely not identical zero.
The only reason for that I can imagine is that in the ADC map
there are some pixels identical zero which have a non-zero value
in the T2 image. May that be the problem?
