[Insight-users] 32 bit (float) TIFFs ? HDF5 ?

[Robert.Atwood at diamond.ac.uk]

Dear All:

I find that attempting to input 32-bit (floating point valued) TIFF images gives me a message indicating that the ITK import method doesn't handle this. Why is this, is it especially difficult or has there just not been demand?  

Though, we are migrating to HDF5 via NeXus  http://www.nexusformat.org/   hoping to get away from the inherent problem of TIFFS (too many files for the poor little data storage system, much too small limits for stacked-tiffs...) but that may have its own problems , I personally can't get the C++ library to say 'hello world' even -- what stage is HDF5 in ITK at? Here, NeXuS is the preferred flavour of HDF5, and so far the performance benefits seem to be worth the convenience costs  (few applications read it) -- so if we really go that route I'd like to try to help ensure that ITK -- therefor hopefully all applications that make use of the library ...  can read this stuff. But I'm not the programmer , I can try to recommend that our programmers lend assistance if it helps increase usability of the data form that works best for the data acquisition side; so I'd like to clarify the current hdf5 situation. 

Regards

Robert
