This document consists of three parts 1. Clipping sequences 2.5. Changes and version history 1. All files, including output-files, are kept in the same directory. 2.1.1 Nucleotide positions and gaps All nucleotide positions conform to the numbering scheme of control region sequences according to Anderson et al .
Most gaps result from additional bases compared to the reference sequence.
The graphic shows the positions where additional nucleotides are observed in HV1 and HV2. The database uses the scheme below to adress each single nucleotide position. This is the most important menu. To make a selection click on the light field next to the categories and a pop-up menu will appear. All entered keywords will be combined, i.e. the records must satisfy all selected categories.
