View single-channel images with RGB colormap

Hello,

I'm trying out OME.

My raw images consists of single-channel floating-point pixels, which I like to visualise using an RGB colormap (for example using imshow() in Python/Matlab). I have not found a way to do this in OMERO. Is it possible?

The alternative would be to convert my data to 8/16 bits TIFF with a embedded colormap before importing to OMERO, but it would be much better to do this as a rendering option that leaves the original data intact.

Thanks!

Guillaume.

By "in OMERO" you mean in one of the OMERO clients?

We agree, but unfortunately it's not yet possible to store a LUT with your rendering options. Our plan for adding it is available on trello: https://trello.com/c/EllVFMjZ/121-rendering-settings. I've linked this post on that card. We'll let you know when there's something to try out.

All the best,
~Josh.

Thanks Josh.

Yes, I meant in the client.
