addXYfromGAL {arrayQualityMetrics} | R Documentation |
From the coordinates of the blocks of a microarray slide and the Row
and Column locations of the spots within the blocks,
addXYfromGAL
computes the X and Y coordinates of the spots of a
slide.
addXYfromGAL(x, gal.file, nBlocks, skip, ...)
x |
is an AnnotatedDataFrame representing the featureData
of an object. |
gal.file |
name of the file .gal that contains the coordinates of the blocks. |
nBlocks |
number of blocks on the slide. |
skip |
number of header lines to skip when reading the gal.file. |
... |
Arguments that get passed on to read.table . |
The object x
of class AnnotatedDataFrame
will be
returned with two added columns: X and Y corresponding to the absolute
position of the probes on the array.
