Hi,
The way you choose to store any data in OMERO really depends on the nature of the data and how you might want to retrieve or query it.
You probably want to use annotations of some type, either plain text (comment) or xml (if that's the current form of your analysis files) or even a File annotation.
You could link a single annotation to all of the images in the chain, possibly including image IDs in the text/xml itself, to indicate which steps apply to which images. OR you could split the analysis file into smaller pieces that describe a single analysis step each, and link each one to the relevant image that was generated from that step.
In a very simple 'analysis chain' I have previously used the description field for the new image to record the ID of the source image and a number of parameters for how it was processed (see the end of
http://cvs.openmicroscopy.org.uk/snapsh ... pting4.mov). If you add "Image ID: 123" to an image description, OMERO.insight client will actually give you a link to that image (we haven't yet done Image-Image links 'properly' in OMERO).
I guess you may not have an image in OMERO for every step in the chain, in which case the first idea might be better.
You can use your own namespace on the annotation to identify them as coming from your analysis chain (helps with querying etc).
Hope that helps,
Will.
