[FieldTrip] extracting the transfomation matrix when using ft_volumenormalize

[Frans Nord]

Dear fieldtrippers,

I was looking into alternatives to go from subject space to MNI space in my
source reconstruction and stumbled upon this old thread
https://mailman.science.ru.nl/pipermail/fieldtrip/2012-October/031673.html
where the following is stated:
"

-Take an individual MRI (that is coregistered to the individual's
head, i.e. it has a transform that defines the head coordinate system
correctly).
-Call ft_volumenormalise (with cfg.nonlinear = 'no')
-The output volume (let's call this variable normalise) contains a
transformation matrix in normalise.cfg.final, that transforms from
head space into 'MNI-space'.

"

When I'm trying to implement this I load a T1 and perform ft_volumerealign
to co-register to acpc coordinates interactively. I then do as suggested
with ft_volumenormalize with cfg.nonlinear='no' but end up without the
matrix in normalise.cfg.final. Am I doing something wrong or has the
functionality changed?

Best,
Frans
