Description
Reads the binary Illumina bead location files and returns a matrix of
the coordinate pairs for every bead on the array.
Usage
1
readLocsFile(fileName)
Arguments
fileName
A string containing the name of the “.locs” file to be read.
Details
The locs file contains bead centre locations for every bead on the
array, unlike the bead level text files, with contain just the beads
that were decoded. Reading these can be useful if one wants to verify
that the image registration was successful, or is interested in the
locations of the undecoded beads.
The locs file itself is in a binary format, with each of the bead
locations stored as a pair of doubles. The first 2 bytes contain
header information, with the 3rd byte containing the number of probes
on the array. The location information begins with the 4th byte.
Value
Returns a two column matrix of bead coordinates, one row per bead.
