        The data are open, but we are always interested in discussions or collaborations. Data collected by @muyuuyum, analyzed by @XiuyeChen and colleagues, collaboration with @EngertLab and @HSompolinsky, @harvardbrainsci and @HHMIJanelia #zebrafish #openscience

        Pardon my ignorance, but how does this data compress so efficiently? Seems like it's 26700% compression?

        I think he's counting the 15TB of raw data and only exports the segmented data (per neuron), but I have to check. In any case, they use Dropbox to share the data, which makes the whole zip impossible to download.

        Exactly, the compression comes from cell segmentation. The data are now on FigShare, https://figshare.com/s/16927195662ea9ff29c7 …, with DOI 10.25378/janelia.7272617, I hope that downloads better. Let us know

        Cool data and analysis! Would be interesting to interactively explore the dynamics. Check out interactome we developed for #celeganshttps://github.com/shlizee/C-elegans-Neural-Interactome …

        Do you consider to analyse some interesting behaviours like instinctions and its relational concepts. Running away from a hunter or hiding in sand for example and implement it to the Human made systems such as AI?
