FMask 4.0 failing on S2 scenes with partial coverage

[dionhaefner]

I noticed that FMask 4.0 standalone fails on some S2 scenes with the error

Cell contents reference from a non-cell array object.

Error in ReadSunViewGeometryMSI (line 171)


Error in nd2toarbt_msi2 (line 44)


Error in LoadData (line 105)


Error in autoFmask (line 96)


Error in Fmask_4_0 (line 10)

MATLAB:cellRefFromNonCell

All of the offending scenes are from orbits only partially covering the tile, like this one:

@qsly09 Thanks a lot for your efforts! Will you also update Fmask_4_0.install (the Linux installer) with the fix?

[qsly09]

Sure. The version on Linux was also updated. Thanks.

[dionhaefner]

@j08lue Will you do some tests? If this version works, we can close this issue.
