vector of lenght 2; specifying which data sets to compare from the ExpressionSet
bound.cutoff
numeric; threshold above probes are considered “bound”
diff.cutoff
numeric; difference threshold to determine if object 1 and object 2 are unqiquely bound
probes
integer; minimum number of probes in a valid region
probe.max.spacing
integer; maximum number of base pairs in a gap before splitting a region into 2 regions
writeBedFile
logical; should bed file be written
Details
Probe signal values above the bound.cutoff in both data are classified as common
bound. Probes which are above the bound.cutoff and in one data and higher than the
diff.cutoff to the other data are called unique. Then these probes are then filtered
into regions using the probes and probe.max.spacing details. The score for the unique
regions is calculated as mean (probes in region set 1 minus set 2), or vise versa.
The score for the common region is the mean (probes in region (set 1 plus set 2)/2).
Optional bed file formated result files are written using the choosen options in the file names.
Value
data.frame with the following columns:
name
name(s) of data set to which region belongs
class.group
class group; 1, 2 or 3 for common regions between both sets
