[Insight-users] Display deformation field

[Karthik Krishnan]

Why don't you just change the meta image header that you mailed
earlier. The datapointer is going to be the same if the extents in the
third dimension are 1. So your new header is.

ObjectType = Image
NDims = 3
BinaryData = True
BinaryDataByteOrderMSB = False
CompressedData = False
Offset = 0 0 0
CenterOfRotation = 0 0 0
ElementSpacing = 1 1 1
DimSize = 768 576 1
AnatomicalOrientation = ??
ElementNumberOfChannels = 3
ElementType = MET_FLOAT
ElementDataFile = kalip_grey_Deformtionfield_ReciprocalSpline_new.raw
