I haven't used mdlScan_initOpenedFile(...) before, but looking at the
help it says that it ZEROS out the scanlist. It looks like it works the
same way as mdlScan_initScanlist(...) and should be used in its' place.
When you use it later in the code you are setting everything back to
default values.
In your _do loop_ check what element types are being returned.
