Can we use No in the filter expression?



Can't we use No(default Number columnn in the capturing window) as a filter(for ex: No >25)? A Custom protocol has a Sequence Number field.This is also added as a column in the capturing window. My Requirement is: I should apply No==25(example) first and then take the Sequence Number from that row. If its not possible this way, please let me know all the other ways to obtain the Sequence Number value from a particular row. Please Help. Thanks in Advance.

One Answer:


The frame number is available as the filter "frame.number" :-)

So you can use : frame.number > 25
