CMCorig data, Coherence Tutorial

Thank you for responding. I have waited to reply as I have steadily worked
my way through the Coherence
Tutorial, and most all of the beamforming tutorial - there a major question
at this point:
My segmented MRI is never aligned with the MRI image it is derived from. I
am using the program MRIcro to convert *.dcm files to an *.img file before I
read it into fieldtrip using the read_fcdc_mri.m function. Then I segment
using spm2 through fieldtrip's volumesegment.m function, and flip dimensions
as discussed in the tutorial. This works correctly for the sample data,
file Subject01.mri, but for my *.img files, when I use sourceplot to see if
the segmented brain fits and the MRI are aligned correctly, they are
unfortunately not. I have tried different flipping methods to no avail.
Thank you in advance,
