[Insight-users] writing meta file

[Sylvain Jaume]

Hi Wanmei,

The .mha file contains the header and the raw data.
Did you try reading your .mha file (and convert it back to PNG) to check 
if the raw data are included?
Another option is to use 'junk.mhd'. Then you should get a 'junk.raw' file.
Let me know how it goes.

Regards,
Sylvain
