I am looking for a way to let a user choose in a model between different, alternative algorithms (or other models). An example would be a simple model which reprojects a vector layer either to WGS84 or NAD27 based on a boolean input field. I know I can use runscript in a custom processing scripts and add the logic with python. But is there a way to do this with a model as well ? Essentially, I am thinking of algorithm which has two inputs of type algorithm (and bool and the actual data layer) which probably need to have the same output types. Or perhaps there is a better way to think about introducing logic in models. Thanks, Andreas
