Yes and No. Of course, the thesis as well as the employed programming codes have to be new but you are not expected to find completely new research results. Your master’s thesis should prove your ability to work independently on an advanced problem from the field of bioinformatics using scientific methods, as well as the ability to represent the obtained results appropriately both orally and in writing. These results are also meant to be documented and evaluated (cf. study/examination regulations 2012).
