Chimpanzee and human sequences were aligned using CLUSTALW with default parameters and adjusted by hand. Simple sequence repeats were removed from the human sequence before the alignment using RepeatMasker. The alignment files are in aligned fasta format. Each file contains chimpanzee and human sequences with gaps in each sequence relative to the other indicated as "-". There are 5 alignment files in total. They are numbered sequentially (alignment1.fa - alignment5.fa) in the order of their position along the length of the chimpanzee sequence. alignment1.fa 1-2895466 alignment2.fa 2895467-4837796 alignment3.fa 4887674-7039289 alignment4.fa 7562270-8871408 alignment5.fa 9036402-9507369 There is a gap in the chimpanzee sequence between alignments 2 and 3. The sequence between aligments 3-4 and alignments 4-5 is deleted in human.
