confusing error message for map_to_aois

[xiaotiansu]

Question

I got an error message that I don't understand when applying map_to_aois

Sample Code

the GazeDataFrame

the text stimulus

the error message

[SiQube]

can you provide me with the IA.ias file and the first gaze file as well as your setup s.t. I can debug locally? if so you can send them by mail to me

[SiQube]

the error message seems to indicate that you did not specify the pixel columns? maybe you can add

pixel_columns = [YOURNAMEFORXPIXELS, YOURNAMEFORYPIXELS]

then it could work

I defined that in the dataset definition, but sent you a github invite

@SiQube Hi, I want to check the status of this issue. I got the following error message when I try to apply ia1 to events. I think that's because my ia1 doesn't have the required columns?

We configured IA using data viewer, it has left, right, top and bottom as shown in fig2. Could you provide some suggestions on how I could convert them to the requirement columns of start_x_column, start_y_column,

etc. in TextStimulus? Thanks!

[SiQube]

how did you load ia1 could you show this definition?

it should be a text stimulus, so it should roughly be:

ia1 = text.from_file(
    aoi_path=PATHTOYOURFILE,
    aoi_column='label',
    start_x_column='left',
    start_y_column='top',
    end_x_column='right',
    end_y_column='bottom',
)

end_x_column='right',
end_y_column='bottom',
)

I loaded them fron .ias file

ia1 = pd.read_csv("../IA/C1_IA.ias", sep="\s+", header=2)

[SiQube]

please use the TextStimulus class and the loading process shown above

[xiaotiansu]

please use the TextStimulus class and the loading process shown above

Thanks! Now I loaded successfully. But got a columnnotfound error
