IndexError #22

Closed ChrisCo74 closed 1 year ago

ChrisCo74 commented 2 years ago

Hi, Program tested: extract_trial_data_and_detect_fixation.py from the 'resources' folder. I tried run the 'testfile.pkl' from same folder and get an error : line 31, in extract_trial_data start_idx = np.where(df_msg.msg == msg_onset) [0] [0] IndexError: index 0 is out of bounds for axis 0 with size 0

I also tried with another .pkl file created after running the antisaccade task demo and have the same error. Thanks for help. Regards, Christophe.

Dear Christophe,

Thanks for your question!

To test with a result (.pkl) file you recorded yourself, you need to modify the messages on lines 86 and 87. Otherwise you will get the error you describe below (indicates that the message you input to the function 'extract_trial_data' cannot be found among the sent messages).

I have updated the help text in the .py-file to clarify this.

Thanks, Marcus
