Filter co-elution feature table according to desired criteria.
1 2 3 4 |
feature_table |
data.table as reported by |
complex_ids |
character vector containing all desired |
protein_ids |
character vector containing all desired |
min_feature_completeness |
Numeric between 0 and 1, specifying the required completeness of a feature reltive to the tested hypothesis (keeps all features if at least one is bigger than the cutoff). |
min_hypothesis_completeness |
Numeric between 0 and 1, specifying the required completeness of the most complete feature reltive to the tested hypothesis (keeps all features if at least one feature is bigger than the cutoff). |
min_subunits |
Integer specifying minimum number of subunits in a co-elution feature. |
min_peak_corr |
Numeric value betwee 0 and 1 specifying minimum peak correlation, defaults to |
min_monomer_distance_factor |
Numeric value specifying a factor to multiply the largest monomer molecular weight, defaults to 2. This filters out features that have their apex at a smaller molecular weight than the resulting min_monomer_distance_factor*max(monomer_mw) value. Using this filtering option can, for example, remove complex features that are likely spontaneous co-elutions of the subunits monomers. |
The same feture table as teh input, but filtered according to the provided parameters.

complexFeatures <- exampleComplexFeatures
## Run summary function:
summarizeFeatures(complexFeatures)
## Filter complex features by a peak correlation of 0.5, a minimum hypothesis
## completeness of 0.5 and a minimum distance to the monomers by a factor of 2:
filteredComplexFeatures <- filterFeatures(complexFeatures,
min_peak_corr=0.5,
min_hypothesis_completeness=0.5,
min_monomer_distance_factor=2)
## Run summary function on filtered data:
summarizeFeatures(filteredComplexFeatures)
