Jos? If I understood what you need if you remove the Constant actor (value 6776) and the link to the xmipp_reconstruct_actor your workflow works well with the SDF director.

Hi all, I have been all the week trying to construct a workflow which just takes an optional parameter. If the parameter is present, it concatenates the parameter with another string and outputs it. If it is not present, just put an empty string. At htis moment I am not able to make it work and don't know which kind of director I need to use... Could you please help me with that?.
