Hi Ben,

Thank you a lot for your extensive answer. I can't figure out how to reply on your reply, so I'm doing it this way.

Well, what you suggest: I've tryed it a couple of times before without succes. What I've now figured out:

• If I code each TRANSCRIBED SEGMENT (e.g., 0:10.0-3:05.0: Introduction, teacher motivates the students to start a new math course -> at the right hand side of the video window), the query is not able to change the cells in "duration" (however, if I select to highlight the coding stripes, it corresponds with correct duration on the timeline). It is however possible to double click on each cell and then I can get access to the duration and the coverage percentage.But this is a very cumbersome way…
• Another way is to change the cells in 'row percentages'. But: this does not give me what I'm looking for. A query that looks as below would give me the following percentages: 25%  50%  25%  0%
                          node 1     node 2     node 3     node 4
  source 1           1               2                1              0         (cell content = coding references)

• If, instead of coding each transcribed segment, I code the corresponding segment on the timeline (which lights up if I select 'play transcript media') then I am able to change the cells in "duration" and this give me already quite some information. But I still will have to calculate manually the corresponding "coverage percentage". But this will not pose too much problems – however I find it strange that it seems to be impossible to simply come up with the coverage percentage as content for the cells.

Briefly:

• If I have coded the transcribed segments, I cannot fill the cells with "duration" (row percentage works, but this gives me not what I want)
• If I have coded the corresponding segment on the timeline (which lights up if I select 'play transcript media') then I am able to change the cells in "duration" – but still not in the coverage percentage of the nod for the source. But this seems me a way to handle this NVIVO-inconvenience.

Best,

Hendrik
