[Insight-users] MetaImage: absolute path in ElementDataFile not working

[Florian Pierron]

Hi Luis,

Thanks for your quick reply.

I am using VC2005 to compile the code. I don't see anything obviously 
wrong with the path, it is:
ElementDataFile = C:\Program Files\Data\MyData.raw

I have attached the .mha file and the .raw image. Let me know if you can 
load it.

Regards,
Florian

***********************
ObjectType = Image
NDims = 2
DimSize = 50 50
ElementByteOrderMSB = False
ElementNumberOfChannels = 1
ElementType = MET_UCHAR
ElementDataFile = C:\Program Files\Data\MyData.raw
***********************
