[Insight-developers] Re: MetaImage magic?

[Stephen R. Aylward]

Hi,

I guess I really don't know why we need another file reader if it offers 
no new capabilities, and as you admit, duplicates much of the syntax and 
capabilities of an existing format.  Put another way, what is the value 
added by nrrd and why should it read the metaObject format?   I truly 
question the purpose of the nrrd format.  I really don't support any 
further duplication of metaimage in it.  I don't think you are making a 
contribution to the field.
