there is not reason at all to do this. the rdf code will have to do

well, then you either made a mistake at this last step and used the
gofr gui incorrectly or already made a mistake when loading the
trajectory. when it processes 0 frames, you operated on an "empty"
molecule. also, have you tested the selections in the GUI? do they
contain any atoms for any frames?
