The MRI Recording Processor has several con
fi
guration options for managing how the artifact
is detected and gated, and for which type of
fi
ltered waveform is output for other downstream
processes. In this con
fi
guration, a threshold crossing is used to trigger the artifact rejection.
MRI gizmo options for threshold crossing
Working Window
determines how much of the signal to view when an artifact is triggered.
Make sure this window is long enough to capture the entire artifact you want to remove.
Optionally save the Timing Epoc to get timestamps when artifacts are detected, stored
synchronously with your data as the default epoc event "Mgt/".
You can save the raw signal for o
ffl
ine analysis and artifact subtraction. You can also
fi
lter/
visualize for Single Unit and/or Local Field Potentials frequency ranges.
