[FieldTrip] Calculating half peak values after applying ft_globalmeanfield

[Craig Richter]

Hi Amie,

Here are a powerful set of peak finding tools (and a cool vintage website!):

https://terpconnect.umd.edu/~toh/spectrum/PeakFindingandMeasurement.htm <https://terpconnect.umd.edu/~toh/spectrum/PeakFindingandMeasurement.htm>

I would recommend playing with ipeak:

https://terpconnect.umd.edu/~toh/spectrum/PeakFindingandMeasurement.htm#ipeak <https://terpconnect.umd.edu/~toh/spectrum/PeakFindingandMeasurement.htm#ipeak>

Which will give you GUI to get a feel for the best parameters for fitting your peaks. Then you can use FindpeaksG.m to automate the peak finding using these parameters.

https://terpconnect.umd.edu/~toh/spectrum/PeakFindingandMeasurement.htm#findpeaks <https://terpconnect.umd.edu/~toh/spectrum/PeakFindingandMeasurement.htm#findpeaks>

These matlab functions will return the specific peak location, height, etc., which you can use as parameters for your window definition, i.e. full-width-at-half-max, etc.

Best,

Craig
