filter_wells: Filter wells

In meaRtools: Micro-Electro Array (MEA) Analysis

Description

Filter out wells for which the number of active electrodes is less than 4, at least 70 percent of the time

Usage

filter_wells(unfiltered_df, nae,min_electrodes = 4, 
well_max_div_inactive_ratio = 0.5)

Arguments

unfiltered_df	Dataframe generated by the spike_features() function
nae	A dataframe containing the number of active electrodes for the recording
min_electrodes	Minimum number of active electrode to consider a well for analysis
well_max_div_inactive_ratio	The DIV inactive/active well ratio below which a well will be considered active for a set of DIVs

Value

A dataframe identical in format to the input, except that wells that do not meet the filtering criteria are removed.

Examples

	data("S")
	data("parameters")
	s<-list(); s[[1]]<-S
	spike_features<-aggregate_features(s, feat_type="spike", parameters )
	nae = spike_features$nae
  filtered.spike.features = lapply(spike_features, function(x) filter_wells(x, nae))
