Hi Kurt,

Thank you for the details on the Volocity format. We are looking into
whether adding support to Bio-Formats is feasible.

Also good to hear about your Openlab LIFF plugin. Have you considered
folding your improvements back into Bio-Formats? We would welcome any
contributions!

The advantage would be that not only would your fixes work within
ImageJ, but also other libraries that use Bio-Formats: VisBio, OME,
VisAD, and hopefully others as time goes on. Moreover, the ultimate
goal of Bio-Formats is to provide a framework for metadata conversion
from any supported third-party format into a standard format
(OME-XML). This strategy will enable universal easy access to common
metadata such as Z and T dimensions, physical pixel sizes (i.e.,
calibration), excitation wavelength and source, lens magnification,
additional hardware information, and more. *steps off soapbox*

Cheers,
Curtis
