[Vv] x and y axes flipped

Hello,

I have converted a 3-D matrix in MATLAB to an MHA/raw file pair. I can 
load the resulting images in vv but I've notices that the x and y axes 
are flipped. The MHA file contains:

ObjectType = Image
NDims = 3
BinaryData = True
DataType = float
CompressedData = False
TransformMatrix = 1 0 0 0 1 0 0 0 1
Offset = 0 0 0
CenterOfRotation = 0 0 0
AnatomicalOrientation = RAI
ElementSize = 1 1 1
ElementSpacing =  1 1 2
DimSize = 370 592 212
ElementType = MET_FLOAT
ElementByteOrderMSB = False
ElementDataFile = orig.raw


I've messed about a bit with AnatomicalOrientation (e.g. setting it to 
ASL) but this doesn't help. One solution might be to flip the x and y 
axes before writing the data. Are there other solutions?

Thanks!
Rob
