Hi Subrahmanyam Gorthi, you are right, this is just a mistake in the documentation. Of course all of these transformations contain rotation and this is also used within MITK. Thank you for the hint. I have changed the documentation of the module within the SVN version of the software. Unfortunately, the online documentation can not be adapted immediately.

But ideally these transformations should contain rotation also as one of the parameters! Is it just a mistake in the documentation, or is it that for some specific reasons MITK does not use rotation at all? For the sake of easy reference, I am quoting here the description from the above mentioned MITK documentation module: As I mentioned above, please note that in the below description, rotation is not mentioned. "--- Rigid means only translation. The order of your landmarks will be taken into account. E. g. landmark one in the fixed data will be mapped on landmark one in the moving data. You have to set at least one landmark and the same number of landmarks in each dataset to enable the Register button which performs the transformation. --- Affine means only translation, scaling and shearing. The order of your landmarks will be taken into account. E. g. landmark one in the fixed data will be mapped on landmark one in the moving data. You have to set at least one landmark and the same number of landmarks in each dataset to enable the Register button which performs the transformation." Thank you in advance for your clarification on whether MITK uses rotation as one of the parameters, while performing rigid and affine based registrations.
