Block order randomization

[B.D.5]

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): 2021.2.3
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?: I want to randomize 2 blocks of trials

What did you try to make it work?:

Followed the procedure [here] and some of the discussions in the forum e.g.(Blocks of trials and counterbalancing — PsychoPy v2021.2)

1. Created 2 Excel files: one to call .xlsx condition files belongs to two blocks (chooseImLan)
chooseImLan.xlsx (8.3 KB)

the other for number of repetitions (nReps_Tasks):
nReps_Tasks.xlsx (8.2 KB)

2. Created loops around each block: and wrote the column names as nReps

3. Created an outer loop covering both blocks: and put the .xlsx file that I created for conditions in the outer loop.

What specifically went wrong when you tried that?: Blocks are not randomized.
I could not use the “one to call .xlsx condition files belongs to two blocks (chooseImLan)” file. I do not know where to include it.

Here is how the setup looks like:

controlTaskIMLAN should be set to random not sequential

this worked thanks. But when I applied this for randomizing the order of 2 routines, the data repeats each trial 5 times.

Routine1:

Routine2:

ControlorderofRoutines:

the file:

Data: The other routine moves to the 3rd row.

Is there a way to fix this?

@B.D.5

Data: The other routine moves to the 3rd row.

Untick “is trials” for the outer loops. This doesn’t work online.

[B.D.5]

I untick all loops that are created for randomizing the order of routines and blocks.

Should I also do it for the loop for randomizing the trial order? I mean the loop that is reading the main conditions file?

[wakecarter]

You need to keep is trials ticked for the loops connected to your conditions files. Try it and you’ll see why.

although I unchecked all ‘is trials’ in randomization loops, pavlovia creates 3 rows for each columns.
I also unchecked ‘is trials’ for condition loops and sync with Pavlovia, I am experiencing the same problem.

[B.D.5]

I am sorry for rising this question up again, but this is a quite urgent issue. Your help is much appreciated

[wakecarter]

Please could you upload an example data file with the issue? Is your flow still as per the earlier image in this thread?

[B.D.5]

There are two blocks in my study and one is randomly coming. Either of them results in a problematic .csv file. Except for the ones with conditions file, is trials is unticked.

All settings for the other block is the same as this one:
1.

3.

Try just having istrials ticked for ret1_rand and ret2_rand (assuming that nReptsImlist and nRepsWlist can only be 0 or 1)

[B.D.5]

Yes, only 1 and 0.

Are you running this offline?

Was that data file created with only istrials ticked for ret1_rand and ret2_rand ?

[B.D.5]

No, online.

yes
also, the ones that include main conditions file also is trials ticked

[wakecarter]

As previously mentioned, the istrials flag doesn’t do anything online.

You can reduce the number of rows online by using different techniques, such as:

if nReptsImlist == 0:
     continueRoutine = False

in Begin Routine of imret2_loop instead of having a loop around it with nReps of nReptsImlist
