The workflow is in the center panel; for its input we select the same
results from Part 1 that we used for the join with the PolyPhen-2
predictions (red arrow). Several of the steps have annotations
explaining what the workflow is doing. The annotation for step 10
tells us that column 5 of the output is what we want to submit to
SIFT, and that column 4 has the original allele data (blue arrow).
There are 10 steps in the workflow, all of which will be run when you
click the "Run workflow" button (green arrow).
