Converts exon expression matrix for a list of exons of interest. If the initial input expression matrix is on probeset level, the component can combine the probeset level data into exon level data. If an exon has replicate probesets, the converted expression is "median", "mean", "max" or "min" of all its probesets.

Usage | Example with default values |
Name | Type | Mandatory | Description |
---|---|---|---|
expr | LogMatrix | Mandatory | Probeset expression matrix from AffyReader. |
sample | SampleGroupTable | Mandatory | Samples used in pipeline. The table contains columns GroupID(key), Type(one of mean,median),SourceGroups(comma-separated list of sample IDs) and Description. |
exon | CSV | Mandatory | A list of exons of interest. |

ExonExpr | LogMatrix | Converted exon expression matrix. |
Name | Type | Default | Description |
---|---|---|---|
CombineType | string | "medianpolish" | Type of method to combine expression of multiple probesets of each exon. "medianpolish","median", "mean", "min" and "max" can be used. When 'exprType' is 'exon', this parameter is not taken into considered in actural computing. |
ExonColumn | int | 1 | The index of column containing exon Ensembl ID in the input exon file. |
ShowUnmatched | boolean | false | A boolean parameter shows if the expression value of those input exons with matched results should be include in the ExonExpr matrix. If 'true', the expression of those exons is set to -1. |
annotation | string | "/opt/sandbox/pchen/MEAPAnnotation_Human_v64" | The path of exon array annotation file. |
