[Insight-developers] Analyze writer header size incorrect on 64-bit system

[Hans Johnson]

Dan,

I will not be able to look at it today, but the header is defined in
Insight/Utilities/itkExtHdrs/itkAnalyzeDbh.h.  It certainly should be 348
bytes long.  The hdr is a struct that only contains:

int
char
short int
float

types in a structure, and these types should have consistent length on both
64 and 32 bit machines.

The header is well documented regarding the information that is supposed to
reside at each byte location.

I may be able to look at this on Thursday if it is not resolved by then.

Hi all, 

  I tried to write an Analyze file today on a 64 bit system.  The header
size was 352 bytes, not 348 as it should be.  Would someone familiar with
the code see where it might be writing an 8-byte value rather than a 4-byte
value?

Thanks,
