Personally - I'm not sure I trust tile_hsps on a translated search -  
or at all - really - you may want to compute the "dominant" strand  
yourself by iterating through the HSPs or using WU-BLAST to get  
logical groups of HSPs which is a better tiling HSP algorithm (the -- 
links option in WU-BLAST).
