[BioC] Matching Arabidopsis CEL files to annotation (for an ExpressionSet)

Dear All,

the comprehensive gene expression matrix available from
uses CEL file names as column labels (e.g. "X0121.CEL"). Is there
a mapping from these to some form of "phenoData" style annotation
available anywhere? I'd like to create an ExpressionSet from (parts)
of this matrix and then to select arrays systematically based on
the annotation.

At this time I even have difficulty getting from the CEL file names to
any form of annotation, so I'd also be grateful for pointers on this.

Best regards & thanks in advance, Jan
