I'm using the spotSegmentation package and all works fine but in the original 2005 Bioinformatics I read:   

 There is an option to dis- play the various stages of the segmentation process for individual spots, as well as to display the entire block of segmented spots at the end of processing.     

The display of individual spots works (but I've set the show argument to FALSE), but I cannot find the argument (or function) to display the entire block.  

Thanks for any help!
