object |
the scData class object. |
min1, min2 |
technical parameters used in estimating the minimum point between the first two modes of the density curve of logTPM for each cell. |
N |
number of cells to consider when determining the threshold value for dropout candidates; used in conjunction with the |
alpha |
a cutoff quantile in the range [0,1]. Thresholds outside this will be adjusted to the quantile boundary. |
fast |
Boolean; if |
zerosOnly |
Boolean; if |
bw_adjust |
bandwidth adjustment factor; CIDR uses the default bandwidth selection method ‘nrd0’ in the kernel density estimation; see |
populates a Boolean matrix with the same dimension as nData.
The value is TRUE
for an entry if it
is a dropout candidate; otherwise the value is FALSE
.
an updated scData class object with the following attributes updated
dThreshold |
a vector of library dependent dropout candidate thresholds. |
dropoutCandidates |
a matrix with the same dimension as nData. The value is |
