This reports the protocol used to align the Maize_Marker features to Oryza_sativa_indica-chromosome-20070724. Tue Aug 7 14:49:21 2007 Source of Maize_Marker : From the link http://www.agron.missouri.edu/files_dl/SequenceMap/SequenceMap20030425.txt, unique genbank accessions were pulled out and sequences were extracted from batch entrez Alignment procedure details --------------------------- 6970 Maize_Marker are aligned to Oryza_sativa_indica-chromosome-20070724 using blat with blat parameters -minIdentity=50 followed by PslReps with -singleHit. This was followed by a filtering procedure described below and applied in general to 'CrossSpecies-Coding' data sets. Initial summary # alignments : 903 # unique Features these alignments represent: 735 % of total features these alignments represent : 10.55 % The length of the matches are distributed as follows Hit_Length # alignments -------- -------- 100 480 150 87 200 98 250 75 300 51 350 41 400 23 450 25 500 9 550 3 600 3 650 2 700 0 750 0 800 0 10000 6 Alignments with matches less than 150 bp are deleted # remaining Alignments : 336 # unique Features these remaining alignments represent: 298 % of total features these alignments represent : 4.28 % Frequency distribution of the remaining features # hits # features -------- -------- 1 269 2 24 3 1 4 4 5 0 6 0 8 0 9 0 10 0 20 0 30 0 40 0 50 0 100 0 Features that hit more than thrice are deleted. # remaining Alignments : 320 # unique Features these remaining alignments represent: 294 % of total features these alignments represent : 4.22 % % Identity distribution of the remaining features % Identity # features -------- -------- 10 0 20 0 30 0 40 0 50 0 60 0 70 0 80 0 90 0 95 121 100 199 Following is the distribution of gaps Gaps # features -------- -------- 1000 281 2000 25 3000 5 4000 2 5000 0 6000 3 7000 0 8000 0 9000 0 10000 0 Following is the final summary # alignments : 320 # unique Features these alignments represent: 294 % of total features these alignments represent : 4.22 %
