Dear VBM users!
I have been using the VBM5 toolbox from http://dbm.neuro.uni-jena.de/vbm/
for preprocessing of images. Now the toolbox has been updated to VBM5.1
and some changes has been made to the Estimate+Write options. Since only
the latest version of the toolbox is downloadable I would like to know how
to perform the same operations in the new version as I have done in the
The changes I have noticed are:
Bias FWHM: Default value changed rom 60mm to 70mm
Bounding Box: Changed from -78 -112 -50 to -78 -112 -70
These are easily adjusted.
My questions are:
Is the setting 'Grey Matter: Modulated Normalised' in the old version the
same as 'Grey Matter: affine+non-linear' in the new one?
What are the default settings in VBM5 (old version) for:
Set Origin: 'Center of mass' or 'Origin from header' ?
Write affine only: 'affine only' or 'warps+affine' ?
These options are not possible to select in the old version.
In VBM5 you could choose Bias Corrected: 'SAVE' what is the equivalent in
the new VBM5.1 version? 'Normalised space: yes'?
Are there more changes in the default settings than the ones I have
I would be very grateful for help!
