Loading Morpheus session files from a URL

[rajivnarayan]

Is it possible to load morpheus session files from a URL location? That would be useful for sharing preconfigured views of data.

• Loading a dataset works, for example: https://software.broadinstitute.org/morpheus/?json={%22dataset%22%3A%22%2F%2Fs3.amazonaws.com%2Frn-test-data%2Ftest.gct%22}%0A

• But it fails if I provide it a Json formatted session file https://software.broadinstitute.org/morpheus/?json={%22dataset%22%3A%22%2F%2Fs3.amazonaws.com%2Frn-test-data%2Ftest.json%22}%0A

However downloading the same session file and manually opening it also works.

You can pass the URL to the session file as: https://software.broadinstitute.org/morpheus/?url=https://s3.amazonaws.com/rn-test-data/test.json

On a related note, is it possible in some way to use the morpheus javascript code from my own javascript program and pass it not a URL, but the data directory, e.g. as a string or a JSON object? I've written a simple t-SNE/UMAP viewer (cells.ucsc.edu) and it would be cool if I could let users explore the data in morpheus. However, I don't have a server backend yet that could create the .tsv file for morpheus.

For example, when running landingPage.open(options), I could add the data itself (as a typed array?) to the options object.

Please see https://github.com/cmap/morpheus.js/blob/master/examples/json_example.html. Please let me know if anything is unclear and I'd be happy to help.
