Advanced loop operation weight always presented in blocks

  Hi Pascal,

  This is intended behavior, but I see not that it's not documented very clearly. The logic is that:

  1. The loop table is first created (randomized or not);
  2. Then constraints are applied;
  3. And finally the advanced loop operations are applied.

  If you want randomize at the very end, you would simply add a shuffle operation below the weight operation, if you see what I mean.

  I'll clarify this on the documentation site.

  Cheers!
  Sebastiaan

  Dear reader,

  This has been helpful in solving my problem of setting a weighted experimental loop in random order by adding shuffle after weight (see code below). I have 3 (panel members) by 3 (valences) = 9 conditions that each appear with a different weighting. When I preview the loop, it is shown in random order(see screenshot).

  However, when running the experiment the weighted loop is still presented in blocks. Would you perhaps have any tips on how to solve this issue?

  Kind regards, Charlotte

  Dear reader,

  I have tried to find a solution but so far no luck to solve the problem above. I am using opensesame 3.2.8. on a macbook Mojave 10.14.6. Any suggestions would be appreciated.

  Kind regards, Charlotte

  Hi Charlotte,

  I have never worked with advanced loop operations, so I can't help you finding out what is happening in your code, but if you like I can try to solve your problem in different ways, i.e. python scripting. Let me know if you would like that.
