Hi Kyle,
Ah, sounds like you are talking about TIFFs compressed with the CCITT_1D
compression scheme (CCITT Group 3 1-Dimensional Modified Huffman run length
encoding). Unfortunately, the Bio-Formats plugin (
http://www.loci.wisc.edu/ome/formats.html) does not currently support that
compression scheme. But if you send me some of your compressed files, I can
work on it and get back to you. In the meantime, you could try a program
like ImageMagick to convert them on the command line into something more
manageable.
Thanks,
Curtis
