I'm trying to run fmask on a Sentinel-2 granule. I downloaded the 3.2 version of Windows stand alone software for Sentinel 2 from https://github.com/prs021/fmask When I try to run fmask by calling the FmaskMSI.exe through cmd from the folder containing the Sentinel-2 Granule (or from within the granule folder) i get the following error:

No L*MTL.txt header in the current folder!
Output argument "clr_pct" (and maybe others) not assigned during call to "autoFmask".
MATLAB:unassignedOutputs

The L*MTL.txt suggests that its's looking for a Landsat type product but i specifically point to the Sentinel-2 installation of fmask

How do i get fmask to run for Sentinel-2 data?
