MultiMAP using precomputed distance matrices

[ulo]

Hi! I would like to try MultiMAP for integrating a variety of datasets on a specific protein family. This includes classical omics data like RNA-seq or targeted metabolomics, and also structural information and protein annotations. For each of the different data modalities, I derived distance matrices which I can generate nice individual UMAPs on (using the metric='precomputed' parameter). And as MultiMAP is a generalization of UMAP, would it theoretically work to create a MultiMAP based on these distances? I am aware that the current implementation does not support this, but I would like to know if conceptually this would be possible. I tried to figure out by looking at your source code, but I am unfortunately neither a mathematician nor a Python expert...

Many thanks! Ulrich
