  1. aThe approaches used to infer the extent of each of the centromeric repeat arrays are outlined in the text (chromosomes 3, 5 and 7) and Additional file 2 (chromosomes 1, 2, 4, 6 and 8).
  2. bThe coordinates were defined using the Tandem Repeats Finder Program [31]. The positions in the sequence where the programme detected the first and the last motif were defined as the beginning and as the end of the centromeric repeat region. Coordinates are from T. brucei 927 version 4 (GeneDB).
  3. cThe size of the centromeric repeat array is not defined in GeneDB due to incomplete gap closure.
  4. dThe coordinates correspond to blast hits with chromosome 4 centromeric repeat sequences. These occur adjacent to a gap of undetermined size.
