**What it does** This tool allows the user to merge MAF blocks which are adjoining in each specified species from a MAF file. Columns which contain only gaps are removed. Species which are not desired are removed from the output. **Example** Specifying the desired species as hg17 and panTro1 with this MAF file:: ##maf version=1 a score=60426.000000 s hg17.chr7 127471195 331 + 158628139 gtttgccatcttttgctgctctagggaatccagcagctgtcaccatgtaaacaagcccaggctagaccaGTTACCCTCATCATCTTAGCTGATAGCCAGCCAGCCACCACAGGCAtgagtcaggccatattgctggacccacagaattatgagctaaataaatagtcttgggttaagccactaagttttaggcatagtgtgttatgtaTCTCACAAACATATAAGACTGTGTGTTTGTTGACTGGAGGAAGAGATGCTATAAAGACCACCTTTTAAAACTTCCC-------------------------------AAATACT-GCCACTGATGTCCTG-----ATGGAGGTA-------TGAA-------------------AACATCCACTAA s panTro1.chr6 129885076 331 + 161576975 gtttgccatcttttgctgctcttgggaatccagcagctgtcaccatgtaaacaagcccaggctagaccaGTTACCCTCATCATCTTAGCTGATAGCCAGCCAGCCACCACAGGCAtgagtcaggccatattgctggacccacagaattatgagctaaataaatagtcttgggttaagccactaagttttaggcatagtgtgttatgtaTCTCACAAACATATAAGACTGTGTGTTTGTTGACTGGAGGAAGAGATGCTATAAAGACCACCTTTTGAAACTTCCC-------------------------------AAATACT-GCCACTGATGTCCTG-----ATGGAGGTA-------TGAA-------------------AACATCCACTAA s mm5.chr6 28904571 357 + 149721531 CTCCACTCTCGTTTGCTGTT----------------CTGTCACCATGGAAACAAA-CGAGGGTGGTCCAGTTACTATCTTGACTGCAGCTGGCAGTCAGTT-GCCACT-----CAGGAATAAGGCTATGCCATT-GATCCACTGAACCGTGATCTGGAAACCTGGCTGTTGTTT-------CAAGCCTTGGGGCCAGTTTGCGGTGTTACTCATGA--CTCTAAGATCGTGTGCTTG----CTGCAGGAAGAGACAGCAAGGGGGTTACATTTAAAAAGCCCCCAGTTTAGCTATAGGCAGGCCAACAGGTGTAAAAATACTCACTAGTAATGGGCTGAACTCATGGAGGTAGCATTAGTGAGACACTGTAACTGTTTTTTTAAAAATCACTAA s rn3.chr4 56178191 282 + 187371129 CTTCACTCTCATTTGCTGTT----------------CTGTCACTATGGAGACAAACACAGGCTAGCCCAGTTACTATCTTGATCACAGCAGCT-GTCAGCTAGCTGCCACTCACAGGAATAAGGCCATACCATT-GATCCACTGAACCTTGATCTAGGAATTTGGC----------------------TGGGGCCAGTTTGCGGTGTCACTCATGA--CTCTAAGATTGTGTGTTTG----CTCCAGGAAGAGACGGCAAGAGGATTACCTTTAAAAGGTTC---------------------------------GGAGTCTAGCTGTAGACAGCCCA-----ATG--GGTA-------TAAC-------------------AATACTCACTAA a score=8157.000000 s hg17.chr7 127471526 58 + 158628139 AATTTGTGGTTTATTCATTTTTCATTATTTTGTTTAAGGAGGTCTATAGTGGAAGAGG s panTro1.chr6 129885407 58 + 161576975 AATTTGTGGTTTATTCGTTTTTCATTATTTTGTTTAAGGAGGTCTATAGTGGAAGAGG s mm5.chr6 28904928 54 + 149721531 AA----CGTTTCATTGATTGCTCATCATTTAAAAAAAGAAATTCCTCAGTGGAAGAGG results in:: ##maf version=1 a score=0.0 s hg17.chr7 127471195 389 + 158628139 gtttgccatcttttgctgctctagggaatccagcagctgtcaccatgtaaacaagcccaggctagaccaGTTACCCTCATCATCTTAGCTGATAGCCAGCCAGCCACCACAGGCAtgagtcaggccatattgctggacccacagaattatgagctaaataaatagtcttgggttaagccactaagttttaggcatagtgtgttatgtaTCTCACAAACATATAAGACTGTGTGTTTGTTGACTGGAGGAAGAGATGCTATAAAGACCACCTTTTAAAACTTCCCAAATACTGCCACTGATGTCCTGATGGAGGTATGAAAACATCCACTAAAATTTGTGGTTTATTCATTTTTCATTATTTTGTTTAAGGAGGTCTATAGTGGAAGAGG s panTro1.chr6 129885076 389 + 161576975 gtttgccatcttttgctgctcttgggaatccagcagctgtcaccatgtaaacaagcccaggctagaccaGTTACCCTCATCATCTTAGCTGATAGCCAGCCAGCCACCACAGGCAtgagtcaggccatattgctggacccacagaattatgagctaaataaatagtcttgggttaagccactaagttttaggcatagtgtgttatgtaTCTCACAAACATATAAGACTGTGTGTTTGTTGACTGGAGGAAGAGATGCTATAAAGACCACCTTTTGAAACTTCCCAAATACTGCCACTGATGTCCTGATGGAGGTATGAAAACATCCACTAAAATTTGTGGTTTATTCGTTTTTCATTATTTTGTTTAAGGAGGTCTATAGTGGAAGAGG
