[Insight-users] meta writers problem

[Stephen R. Aylward]

Hi,

This was actually how I intended metaImage to work.   I find it 
safer/simpler to append .raw to files, than to try to substitute the 
last three letters or enforce a naming convention.   There is a bit of 
history to this as well - traditionally, .mha is reserved for metaFiles 
in which the header and the data appears together (metaHeaderAll) and 
.mhd is reserved for metaFiles containing only header data (metaHeaDer) 
and that point to data (.raw) files.   But to try to enforce this I 
would have to sometimes convert suffixes from .mhd to .mha, or append 
one or the other suffix and possibly .raw.   To understand that behavior 
seemed more complex, so I went with something simple...

You can also do a "m_Writer->SetDataFileName("LOCAL");" and it will 
write your header and data to the same file and that way the .raw file 
won't be created - it that more appropriate for what you intend?

Thanks,
Stephen
