Alignment procedure details 
--------------------------- 

71655 Maize_tug are aligned to Maize_BACs using blat with blat parameters -minScore=120 followed by PslReps with -singleHit. This was followed by a filtering procedure described below and applied in general to 'Coding-SameSpecies' data sets.
