FindPeaks

Automatic peak finding for 2D SEC-SAS data.

class find_peaks.FindPeaks(data, height_factor=0.5)

Finds the peaks in a time series from a 2D SEC-SAS dataset.

Parameters

  • data (sample.Sample) – An instance of sample.Sample containing a 2D dataset where the first axis is assumed to be the elution time and the second axis is assumed to be the momentum transfer q values.

  • height_factor (float) – A float between 0 and 1. This will be used to define the minimum height of the peak by taking height = height_factor * data.max().

get_sub_arrays()

Return the array corresponding to the region within peak borders.

run(find_peaks_kws=None, peak_widths_kws=None)

Run the algorithm to find the peaks and associated widths.

Parameters

  • find_peaks_kws (dict) – Additional keywords to be passed to scipy find_peaks keywords.

  • peak_widths_kws (dict) – Additional keywords to be passed to scipy peak_widths keywords.
