Below are a list of circumstances and clarification on whether or not the high-resolution scanning patch needs to be applied. Keep in mind that the high-resolution scanning patch must only be applied on top of GCOS — not Micro Array Suite — software.
a. GeneChip Scanner 3000 (serial number 502xxx): The instrument service engineer has applied the high-resolution scanning patch to the computer that is controlling the GeneChip Scanner 3000 at installation, but not to the workstations or servers (see c and d below).
b. GeneChip Scanner 3000 (serial number 501xxx): The instrument service engineer will apply the high-resolution scanning patch to the computer that is controlling the GeneChip Scanner 3000 at the time of the upgrade, but not to the workstations or servers (see c and d below).
c. Analysis workstations and clients: require the high-resolution scanning patch. This patch has been incorporated into GCOS 1.1.1. If you are running GCOS 1.0, you must apply the high-resolution scanning patch.
d. Server upgrade: Your database administrator or an Affymetrix Software Support Engineer needs to apply the high-resolution scanning patch in coordination with the upgrade of server to GCOS.
e. Installation of library files post scanner installation or upgrade: The high-resolution scanning patch must be reapplied following the installation of library files for arrays that precede Human Genome U133 Plus 2.0 and U133A 2.0 Arrays. The library files for the Rat 230 2.0 Arrays, other 2.0 arrays, and custom arrays with 11 micron features are high-resolution-scanning ready. Other library files that are installed post scanner installation of upgrade will require that the high-resolution scanning patch is reapplied. If you have any doubts about whether the patch is needed or not, simply reapply the high-resolution scanning patch. The error message "cannot read the parameters for probe array type from the database" appears when one tries to scan an array on a GeneChip Scanner 3000 high-resolution scanner but the high-resolution scanning patch has not been applied. |
