Hello, My first Q is, to randomize the 2 routines under ret1_rand and ret2_rand. Although everything was set the same way, randomization under the ret2_rand loop was successful but ret_1rand repeats each routine twice, why? code in Each frame (also tried in begin routine): if nRepsImlist == 0: #i…

to randomize the blocks, I added if nRepsLan == 0: continueRoutine = False this code in every routine – each frame under Block2 and if nRepsIm == 0: continueRoutine = False under the every routine – each frame of Block1. did not work either

Hi @B.D.5 , Let’s start with your first question. Could you please clarify what you are trying to achieve? You write: [image] B.D.5: My first Q is, to randomize the 2 routines under ret1_rand and ret2_rand. Although everything was set the same way, randomization under the ret2_rand loop was suc…

Now your second question: [image] B.D.5: The second Q is I wanted to randomize 2 blocks in the same way. do you mean that you want to have random order of the blocks? So that sometimes block B2 is first and sometimes B1? There are two relatively easy ways to achieve this: have three blocks…

Thank you so much for the answer, as you see in the images, they all are set to random but loop in the first block is repeating itself 2 times but not in the second block. The code is reading the excel file in the outer loop. If the relevant nReps is 0,it passes the that routine and starts with the…

[image] mmagnuski: If your B1 and B2 are identical in structure (as your screenshot suggests) - then maybe you just need one block and a few variables to control whether this block behaves as B1 or B2. I understood your point, In my comment below, I tried to do it but I guess in the wrong way…

Just to make sure we are on the same page: loop is used to repeat a routine or a sequence of routines (with different variables for example), not to randomize the order of these routines loopType set to “random” does not specify number of repetitions, only how rows are drawn from the excel file th…

BTW, you don’t need the code that you paste in each frame of the loop - just set nReps in the loop gui to the relevant variable (for example nRepsLan).

The reason @B.D.5 is using that code is to remove excess blank lines in the data file that you get from the method of variable nReps. [image] Block order randomization Builder As previously mentioned, the istrials flag doesn’t do anything online. You can reduce the numbe…

For my second Q: I want to randomize the order of Blocks as indicated in the image. Sometimes B1 will come, sometimes B2. However, creating several inner and outer loops ended up problematic data output . That is why I wanted to randomize the blocks with a code. So, ret1 and ret2 do not matter they …

Thanks for clarifying, I noticed that pavlovia does not support “is trials” loop option, but I didn’t know this is a workaround for that.
