getMeasurements does not work with background measurements

[atsanda]

I am trying to load an mdf which contains background measurements only using

c = getMeasurements(c_mdf, false; tfCorrection=false, spectralLeakageCorrection=false)

I get the following error:

ERROR: BoundsError: attempt to access 3300000-element Vector{Bool} at index [3300001]
Stacktrace:
 [1] getindex
   @ ./essentials.jl:13 [inlined]
 [2] measBGFrameIdx(f::MDFFileV2{Array{Int16, 4}})
   @ MPIFiles ~/.julia/packages/MPIFiles/Ag3SE/src/Derived.jl:52
 [3] top-level scope
   @ /.../Main.jl:5

I think it is caused by measBGFrameIdx

The problem appears in newer versions because, when downgraded to MPIFiles v0.14.1, it is no longer reproducible

While I was changing stuff in Derived.jl I removed the manual implementation of measBGFrameIdx and just used Julia's findall. If you could check if this fixes your issue that would be great :)
