Detect downward peaks

[MannyEsguerra]

Is there a built in way to detect negative-going peaks in GuPPy, either by inverting the signal or with thresholding?

[venus-sherathiya]

you mean negative peaks in z-score trace ?

[MannyEsguerra]

Does GuPPy only detect positive-going peaks In the signal_xxx ?

[venus-sherathiya]

yes, it only detects positive-going peaks in signal_xxx. You can try inverting the signal and see what it works. But I am not sure how good will it work

[MannyEsguerra]

Is there a way to invert a signal inside Guppy?

[venus-sherathiya]

Unfortunately, there is not. You can write your own small piece of code to do that
