Hi,

I'm trying to support reading OME-TIFF, and I've got a question about channels. The tubhiswt OME-TIFF example files have "LogicalChannel" child elements under the Image element. I don't see "LogicalChannel" in any of the on-site document or the ome schema.

OTOH, I do see "Channel" in the schema, as well as in the specification of "OME compliance".

Are they both active?

Also, the LogicalChannel element's "ChannelComponent" specifies which channel index the logical channel is describing, but I don't see anything similar in the Channel element. Would you just assume that the channels are listed in the order in which they are found in the file?

Thanks,
John

The tubhiswt examples use the older schemas. The 2008 versions in fact. Since 2008 we have removed the LogicalChannel element entirely (it was just something that confused people and had limited utility). Depending on which version of the OME-XML schema you wish to target for your reader you'll want to look at the year by year example files linked here:
