Chapter 9: Trim, Merge & Join runs
Merge Runs
Multiple Runs can be ‘merged’ together to form a new ’averaged’ Run. This function is
particularly useful when multiple Runs have been performed and only slight variations exist,
you may wish to create an average of these to smooth out the variations. Many testers do
multiple Runs after any modification to ensure consistency, merging compliments this practice
perfectly.
A merged Run will be based on up to 4 visible traces (2, 3, or 4). It is required that trace set “1” be loaded and visible as
this is used as the ‘master’ when DYNertia3 generates the new data (any of your recorded comments will copy from this
to the new file). The files merged will be all of the ones visible on the Graph Window. The new averaged Run will be
loaded as the ‘last run’ trace automatically. After the new averaged Run is created you will be asked if you want to hide
the other graph Runs so only the new one remains visible.
Tip- The menu option “View/Clear Graphs” (or ‘Delete’) can be used to clear all of the graph traces so you can pick
entirely new ones to merge if you wish.
Note: ‘Point by Point’ Runs (those done in brake mode by storing individual data sets) cannot be merged. They can
however be joined, that is to combine all data into 1 set. This is done with the in the menu option “File/Join Runs”
The new ‘averaged’ Run will appear as a complete data file and is treated just like any other Run. The General
comments field of the new files notes will automatically have appended a list of the files that it was generated from.
There are different methods used to indicate that a file is the result of merging multiple Runs, depending on the screen-
An “!” symbol will appear next to the run when a ‘graph summary’ is viewed and ‘DYNertia3 File explorer’ has a
note on top of the preview graph.
For indication purposes the weather correction data from the chosen runs is also averaged into the new weather fields
as is the actual correction figure generated by them.
Tip- It is not suggested to merge runs that have been performed under different weather correction standards i.e. don’t
merge SAEJ607 runs with DIN 70020 etc. as the result will be meaningless for analysis, as will be the result if the
original runs vary greatly from each other.
