[ARGUS] ratop is not producing any output

[obaid rahman via Argus-info]

I am trying to view my argus data using ratop but I get nothing when I runt he below commands ratop -S localhost:561 (after running argus server capture using argus -P 561 -d)
ratop -r abc.argus 

However, when using ra -r abc.argus I get the desired output.
