Numerical metadata

Postby chrism » Thu May 10, 2012 11:18 am

Hi All,

I want to store numerical metadata with my images. For example, for each image I have several 128x128 and 512x512 matrices with float and int values. For now I am storing these matrices as Structured Annotations and reconstruct the matrices when needed in computations.

One advantage of this is that all data can be combined in one OME-TIFF file. But it feels very unnatural to handle these data like this and the annotations are very cluttered.

Is there a better way to handle numerical metadata?

Thanks in advance for any help.

OMERO.tables doesn't yet provide an API, but if you can encode your matrices as a single array, it'd like be more efficient to store it in HDF5. Once the ArrayColumn type has been added, a MxN matrix will definitely be more efficient as HDF5.

Cheers,

OK. I will try to use OMERO.tables with one dimensional arrays. Thanks a lot.
