View source: R/findComplexFeaturesSW.R
Detect subgroups of proteins within a matrix of protein intensity traces by sliding a window across the SEC dimension. Within each window proteins with traces that correlate well are clustered together.

min.sec = 1)
|
trace.mat |
A matrix of all traces in a complex hypothesis with small perturbations added to all 0 values for correlation calculation. |
corr.cutoff |
The correlation value for chromatograms above which proteins are considered to be coeluting. |
window.size |
Size of the window. Numeric. |
with.plot |
T (TRUE) or F (FALSE) whether to plot the correlation tree. |
min.sec |
The lowest SEC number in the sample. |
noise.quantile |
The quantile to use in estimating the noise level. Intensity values that are zero are imputed with random noise according to the noise estimation. |
An object of type complexFeaturesSW
that is a list
containing the following:
feature
data.table containing complex feature candidates in the following format:
subgroup
The protein_ids of the feature separated by semi-colons.
left_sw
The left boundary of the sliding-window feature.
right_sw
The right boundary of the sliding-window feature.
score
The intra-sliding-window-feature correlation.
window.size
The window.size used when running this
function.
corr.cutoff
The corr.cutoff used when running this
function.
