[Insight-users] Registration example in ITK User guide

[Xi LIANG]

Dear Luis,
Thank you for your suggestion, and I have downloaded slicer and ParaView. However, I still cannot manage to visualize the example images. I provide the head file information and the property parameters I used in Paraview belowing
The followings are head file informationsNDims = 3DimSize = 181 217 180ElementType = MET_UCHARElementSpacing = 1.0 1.0 1.0ElementByteOrderMSB = FalseElementDataFile = brainweb1e1a10f20.raw

The following are the parameters I used int he property tab. (Kitware ParaView 3.6.1)File Prefix: dir/brainweb1e1a10f20.rawFile Pattern: %s    <---- I am not sure whether this is correctData Scalar Type: unsigned charData Byte Order: LittleEndian File Dimensionality: 3Data Origin: 0 0 0Data Spacing: 1 1 1Data Extent 0 180 0 216 0 179  <----- I deduct one from the DimSizeNumber of Scalar Components: 1Scalar Array Name: ImageFile  <-----Not sure about thisFile Lower Left (ticked)
Then or others are by default
