For this model, I use the nodes located at the bottom of the panel zones, throughout the left column line as centroid nodes as well as response nodes. Therefore, not all the nodes on the left column line are included in loading and response monitoring (e.g. nodes on the panel zones are not included). Could this the problem?
I used the WE-UQ three-story example, and eliminated one of the nodes to see what happens. i.e, instead of 1 2 3 4 as centroid nodes, I wrote down, 1 2 4, and modified the recorder and postprocess files accordingly. So with this conditions, no recorders were generated for me. That is why I assumed that either all the nodes on the column line should be included in the centroid and response sections, or I am modifying the recorder and postprocess files incorrectly.
