For Julia core it should be feasible, but possibly requiring patches to Emscripten, so the level of effort is still unknown. The other issue is the C and Fortran numerical libraries -- some of which use inline-assembly, others (Fortran) don

I'm not aware of anyone working on it. There were some attempts with Emscripten which ran in to unsupported instructions; some of those may be supported by newer versions of Emscripten, but I haven't heard of any attempts to get t

FWIW, typical raw fMRI data is mostly useless unless you know the design parameters of the study (stimulus timing, imaging onsets, etc.). Though there are some interesting data-driven analyses techniques, especially for resting-state data.
