		IGDACProbe

OVERVIEW

The IGDACProbe interface provides access to probe data of cell intensity files and QC probe data of chip files.

Probe data from a CDF file only includes the X/Y coordinate and the PBase and TBase values. Other values such as intensity data are not available when the object is from the IGDACCDFFile object.

PosY

ID	2
Description	The y-coordinate of the probe.
Type	long
Access	Read-only
Remarks	By default, it returns LONG_MAX when it has not been initialized and set by the IGDACCELFile, IGDACCHPFile or IGDACCDFFile interfaces.

Intensity

ID	3
Description	The cell intensity of the probe.
Type	float
Access	Read-only
Remarks	By default, it returns FLT_MAX when it has not been initialized and set by the IGDACCELFile, IGDACCHPFile or IGDACCDFFile interfaces.

Pixels

ID	4
Description	The number of pixels used to calculate the intensity of the probe.
Type	long
Access	Read-only
Remarks	By default, it returns LONG_MAX when it has not been initialized and set by the IGDACCELFile, IGDACCHPFile or IGDACCDFFile interfaces.

StdDev

ID	5
Description	The standard deviation of the probe intensity value.
Type	float
Access	Read-only
Remarks	By default, it returns FLT_MAX when it has not been initialized and set by the IGDACCELFile, IGDACCHPFile or IGDACCDFFile interfaces.

Outlier

ID	6
Description	A flag indicating if the probe was called an "outlier" by the MAS software.
Type	BOOL
Access	Read-only
Remarks	Valid for regular probe only. By default, it returns FALSE when it has not been initialized and set by the IGDACCELFile, IGDACCHPFile or IGDACCDFFile interfaces.

Masked

ID	7
Description	A flag indicating if the probe was "masked" by the user.
Type	BOOL
Access	Read-only
Remarks	Valid for regular probe only. By default, it returns FALSE when it has not been initialized and set by the IGDACCELFile, IGDACCHPFile or IGDACCDFFile interfaces.

Background

ID	8
Description	This value is not currently not set by the SDK.
Type	float
Access	Read-only
Remarks	This value is not currently not set by the SDK.

ProbeType

ID	9
Description	A flag to indicate the type of probe.
Type	GDACFILES_PROBE_TYPE
Access	Read-only
Remarks	By default, it returns UNKNOWN_PROBE_TYPE when it has not been initialized and set by the IGDACCELFile, IGDACCHPFile or IGDACCDFFile interfaces.

PBase

ID 10

Description The probe base at the substitution position.

Type BSTR

Access Read-only

Remarks The value is one of 'A', 'C', 'G', 'T' or blank.

TBase

ID 11

Description The target base where the probes substitution base is designed for.

Type BSTR

Access Read-only

Remarks The value is one of 'A', 'C', 'G', 'T' or blank.
