       alternatives like wrapping this in conditionals, repeats (to force a refresh_on_change as this option 
       is not working on its own) failed since the workflow editor does not support refreshes...not does the

  <help>
Performs a lookup of the RI values by matching CAS numbers from the given NIST identifications file to a library.
If a direct match is NOT found for the preferred column name, a regression can be done to find
the theoretical RI value based on known RI values for the CAS number on other column types (see step 4).
If there is no match for the CAS number on any column type, then the record is not given a RI.
