[Insight-users] raw data to .img

[Atwood, Robert C]

According to

 http://www.bic.mni.mcgill.ca/brainweb/about_data_formats.html 

"The header information is not downloaded, but just displayed at the top of the download page"
You may need to write your own header based on the information displayed in the webpage when you download. Here's one I did for my own purposes, allowing the raw, unsigned, byte file called 'thr_Vthin.raw' to be easily read by an ITK file reader, you would need to change ElementDataFile to point to your file, I believe this needs to be the last line in the file. In my case the voxel spacing is uniform  so you would need to change ElementSpacing accordingly (and of course DimSize)
I just save this text in 'thr_Vthin.mhd' and use that filename in myreader->SetFileName()
 

ObjectType = Image
NDims = 3
BinaryData = True
BinaryDataByteOrderMSB = False
TransformMatrix = 1 0 0 0 1 0 0 0 1
Offset = 0 0 0
CenterOfRotation = 0 0 0
AnatomicalOrientation = RPI
ElementSpacing = 1 1 1
DimSize = 100 100 100
ElementType = MET_UCHAR
ElementDataFile = thr_Vthin.raw
