- fissa.deltaf.findBaselineF0(rawF, fs, axis=0, keepdims=False)[source]#
Find the baseline for a fluorescence imaging trace line.
The baseline, F0, is the 5th-percentile of the 1Hz lowpass filtered signal.
- Parameters
- rawFarray_like
Raw fluorescence signal.
- fsfloat
Sampling frequency of rawF, in Hz.
- axisint, default=0
Dimension which contains the time series. Default is
0.- keepdimsbool, optional
Whether to preserve the dimensionality of the input. Default is
False.
- Returns
- baselineF0numpy.ndarray
The baseline fluorescence of each recording, as an array.
