[ome-users] searching bug

[Martin Spitaler]

Thanks, Will.

  Ideas for missing search features: First, some traditional functions:

  * IMAGE TYPE, e.g. time series, stack, multi-channel...; maybe even
    specifying a specific range (number of channels or time points)
  * METADATA SEARCH, e.g. a specific microscope, lens or excitation
    laser; would also help with the above (e.g. search for "confocal
    images with the 2 channels GFP+DAPI"
  * ADVANCED SEARCH, i.e. the user can search for different things in
    different fields, PUBMED-style

And then an idea that came from one of our users, saying the typical 
situation is having an image and wanting to find related ones, but not 
remembering how to search for them (I seem to remember this has already 
been discussed at OME meetings):

  * SIMILAR IMAGES: some of this functionality would be covered by
    METADATA and IMAGE TYPE search above, but an additional feature that
    sounds doable is mean and standard deviation of intensities

  I know this last idea opens a whole new world of complexity, and also 
workload for servers if calculated automatically (although once done, it 
would only be two more numbers per frame to store), but maybe one or a 
few of the scripting aficionados could help with this? Would it be 
possible to run a script on a dataset calculating such values and adding 
them to the metadata? Long-term, the ideal situation would be to have a 
tick box on data import to do this calculation if wanted, and a script 
to do it later if not ticked on import.

  Obviously there is no limit to ideas, in an ideal world (now still 
dream land), analysis results could be linked to images and allow 
searches like "images with >100 cells" or "cells with 'roundness>1.5'. 
And in a world where photographic cameras take pictures when people 
smile, it's not inconceivable to have basic analysis like counting 
nuclei on import. But that's something after version 4.5 (and 5) - maybe 
someone in the community wants to have a play?

Good work,

Martin
