**What it does** This tool takes a MAF file and creates a new MAF file, where each block has been reversed complemented. **Example** This MAF Block:: 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 becomes:: a score=8157.000000 s hg17.chr7 31156555 58 - 158628139 CCTCTTCCACTATAGACCTCCTTAAACAAAATAATGAAAAATGAATAAACCACAAATT s panTro1.chr6 31691510 58 - 161576975 CCTCTTCCACTATAGACCTCCTTAAACAAAATAATGAAAAACGAATAAACCACAAATT s mm5.chr6 120816549 54 - 149721531 CCTCTTCCACTGAGGAATTTCTTTTTTTAAATGATGAGCAATCAATGAAACG----TT ------ **Citation** If you use this tool, please cite `Blankenberg D, Taylor J, Nekrutenko A; The Galaxy Team.
