README file for AGE software distribution ABOUT Software AGE implements optimal algorithms for aligning genomic sequences with structural variations (SVs). Precise alignment allows for correct breakpoint determination. The algorithms are described in the publication Bioinformatics. 2011 Mar 1;27(5):595-603. Epub 2011 Jan 13. Additional info on importance of breakpoints can be obtained from * Nat Biotechnol. 2010 Jan;28(1):47-55. Epub 2009 Dec 27. * Nature. 2011 Feb 3;470(7332):59-65. The software runs on linux based systems. 1. Compilation ============== $ make or (without parallel support) $ make OMP=no which ever works 2. Running ========== $ ./age_align file1.fa file2.fa The input files must be in FASTA format and can contain multiple sequences. The output is alignments for each pair of sequences with first sequence from the first file and second sequence from the second file. When aligning long read or assembled conting to a chromosome, useful options are -coor1 and -coor2. These options allow specifying region(s) of the inputed sequences, to be used in an alignment. For example, for a prediction of a deletion in the region chr12:11396601-11436500 and assembled conting for the allele containing this deletion, one may use the following command ./age_align chr12.fa conting.fa -coor1=11395601-11437500 i.e. align conting to the the predicted region extended by 1 kb downstream and upstream. The penalty model used for determining the cost of insertions and deletions is the affine gap model. The gap penalty function G(i) is defined as G(i) = go + (ge x i). Note that when there is a single gap then G(i) = go + ge Help: $ ./age_align Options: -indel assume deletion or insertion (default) -tdup assume tandom duplication -invl assume inversion with conting (second sequence) spanning over left breakpoint -invr assume inversion with conting (second sequence) spanning over right breakpoint -inv assume inversion; tries alignment over the left and right breakpoints; report the best alignment -coor1=start-end align subsequence of first sequence defined by given coordinates -coor2=start-end align subsequence of second sequence defined by given coordinates -revcom1 align reverse complement of first sequence -revcom2 align reverse complement of second sequence -both align first sequence to second one and its reverse complement; report the best alignment -match score for nucleotide match -mismatch score for nucleotide mismatch -go=value gap open penalty, negative value -ge=value gap extend penalty, negative value -allpos always display boundary positions -berg align the sequences using Hirschberg's linear memory algorithm Examples: ./age_align -coor1=20-2350 file1.fa file2.fa ./age_align -coor1=20- file1.fa file2.fa ./age_align -coor2=-240 file1.fa file2.fa ./age_align -revcom1 -revcom2 file1.fa file2.fa ./age_align -both file1.fa file2.fa ./age_align -inv -both file1.fa file2.fa ./age_align -tdup -both file1.fa file2.fa Please send your comments and suggestions to alexej.abyzov@mayo.edu.
