+IBS files may contain some rows with Illumicodes that are not represented in the 
+BGX files. 
+Our interpretation is that some probes that used to be annotated with a gene has 
+later been considered poor by Illumina (as we have only observed an increase 
+in the number of unmatched probes for later bgx revisions). To avoid that the 
+raw data importer fails cause of some probes, listed in the IBS-file, couldn't 
+be found in BASE - you have to set plug-in parameter 'Probe not found=skip', 
+when importing data from an IBS-file into BASE.
 
 A new raw data type has been defined in illumina-raw-data-types.xml
