I'm not sure if this is what you want since I create the transformed MRI using the ELEKTA utility and that isn't quite what you're asking.
But you can use the mne utility mne_show_fiff to get the head --> MRI transform matrix from that .fif file:
mne_show_fiff --verbose --in MRI_transform_file.fif
This will show you a bunch of stuff including something like:
222 = transform head -> MRI (surface RAS)
0.99768 0.06237 0.02740 -2.29
-0.06093 0.99686 -0.05052 27.37
-0.03046 0.04873 0.99835 -28.78
0.00000 0.00000 0.00000 1.00
You can also use the ELEKTA show_fiff utility. The switches are slightly different:
show_fiff -v MRI_transform_file.fif
It provides the same plus the inverse transform too:
222 = transform head -> MRI
0.997677 0.062365 0.027399
-0.060927 0.996863 -0.050517
-0.030463 0.048730 0.998347
-2.290811 27.368591 -28.776358 (inv. 3.076347 -25.737595 30.174137)

Subject: [Mne_analysis] create --trans file from COR sets
What is the easiest way to create a text transformation matrix file from already transformed COR sets (that is: ones saved with "Save MRI set")?
