if exist(nirsInfo.RawDataInfo.checking,'var') == 1
    disp("file exists");
else
    disp("doesnt");
end
Here since the .checking doesn't exsist it throwing Reference to non-existent field 'checking' error.

        ‘isfield' can be used to check if a field exists within a structure.  
Refer to the following documentation for more information on ‘isfield’
