A computer implemented method of identifying a structural genomic rearrangements in massively parallel nucleic acid sequencing data, comprising: (a) obtaining massively parallel sequencing information for one or more genomic regions as nucleic acid sequence reads; (b) aligning said nucleic acid sequencing reads to one or more reference sequences; (c) selecting nucleic acid sequencing reads which only partially map to said reference sequence, wherein a portion of the nucleic acid sequencing reads remains unmapped, constituting a soft-clipped region, wherein the soft-clipped nucleotides of the nucleic sequencing read is at least 8 to 15 nucleotides long; (d) creating groups of nucleic acid sequencing reads as selected in step (c), all of which are defined by identical start or end positions of said soft-clipped regions; (e) generating a synthetic consensus sequence for each group as obtained in step (d), wherein said consensus sequence is based on the abundance of identical nucleotides at a position; Characterized in that it further comprises: (f) identification of pairs of synthetic consensus sequences as candidates for structural genomic rearrangements by generating combinations of positions between (i) groups of nucleic acid sequencing reads, wherein soft-clipped nucleotides are at the start of the nucleic acid sequence, and (ii) groups of nucleic acid sequencing reads, wherein said soft-clipped nucleotides are at the end of the nucleic acid sequence, by comparing the synthetic consensus sequence of step (e) with the reference sequence; (g) pairing nucleic acid sequencing reads which match at respective positions in the reference sequence; and (h) detecting a structural genomic rearrangement if both synthetic consensus sequences of pairs as obtained in step (g) match at respective positions in the reference sequence.
