computeAffinities.AffymetrixCdfFile {aroma.affymetrix} | R Documentation |
Calculates probe affinities from sequence.
Adapted from compute.affinities
in the gcrma package.
Attempts to find the tab-separated probe sequence file associated with
a particular CDF, and matches sequence to probe index in order to assign
an affinity to each probe.

paths |
A character variable containing location(s) to look for
the probe sequence file. Multiple locations should be separated by
semi-colons. |

If FALSE , cached results is returned, if available. |
verbose |
See Verbose . |

Returns a numeric
vector
of (log2) probe affinities, of length equal
