After attending the EMBO workshop in Dresden in 2014, I've been using the plugin for two years now and it is an essential part of our light sheet workflow. In a nutshell, we image insect embryos, embedded in agarose containing sub-resolution beads, using single-sided illumination with 8 or 16 angles per time point. In order to infer the biological relevance of RNAi phenotypes, we tend to look at many different specimens for few time points, rather than collecting time-lapse data for a small number of specimens. In practice, this means a lot of reconstructing and adjusting settings, although I find that, for most of our datasets, default settings work nicely for bead detection, registration and deconvolution ("Nicely" in this case meaning a significant increase in local contrast). Sometimes, however, registration is sub-optimal (and who knows, maybe it is also for the analyses that I normally quality as "nice''-). In these cases, as a first hint, inspection with the BigDataViewer reveals that the psf's of the different angles don't overlap properly.</div><div><br></div><div>- Does this sound familiar to other users of the plugin?</div><div>- What reconstruction parameters do you generally tinker with first?</div><div>- for example: do you spend a lot of time on bead detection (and subsequent exclusion)?</div><div>- Do you sometimes reject datasets for multi view reconstruction and if so, on what grounds? For example, I like to image "a lot" of agarose surrounding the embryo in order to have a large set of beads for reconstruction, but am not always very systematic about this. Is this crucial in your data acquisition?</div><div><br></div><div>any ideas appreciated, basically to make better use of this great tool.</div><div><br></div><div>cheers,</div><div>Maarten</div><div><br></div><div apple-content-edited="true">
