This is a controlled combinatorial explosion to find molecular formula for peaks that were left un-assigned by the database and ECS approaches. It uses combinatorial sub-set sum solutions using 16 selected atoms for one m/z value. This is a slow process and should only be used for one file at time.
Follow these steps.
STEP1: Install the UFAx secondary package .
STEP2: Prepare the input parameter file
STEP3: Run the UFAx workflow
