pspm_trim error: Matrix index is out of range for deletion.

[evl98]

Hello,

I am trying to import and trim my SCR data from a biosemi device (.bdf file). However, whenever I try to trim the data it gives the following error:

Matrix index is out of range for deletion.
In file "C:\Users\0072494\OneDrive - Universiteit Utrecht\Documents\MATLAB\PsPM\PsPM_course_ESCAN2024\PsPM_v6.1.2\pspm_trim.m" (???), function "pspm_trim" at line 328.
In file "C:\Users\0072494\OneDrive - Universiteit Utrecht\Documents\MATLAB\PsPM\PsPM_course_ESCAN2024\PsPM_v6.1.2\pspm_cfg\pspm_cfg_run_trim.m" (???), function "pspm_cfg_run_trim" at line 45.

This happens regardless of the references I put in. The only way in which the data does trim, is when I only import my SCR channel, without the markers, and then use the time period from the start of the file as a reference. For this reason, I am suspecting there to be an issue with the import of the marker channel from my .bdf file; as even just using the start of the file as a reference gives this error whenever the marker channel is included.

Does anybody have an idea what is going wrong and how I could solve this?
Thanks!

Emily

Hi Emily
thanks for reaching out. I agree this is probably a problem with the import. Would you be able to send the problematic raw data file and your import script, via email or direct download? Or any sample file.

Dear Dominik, Thank you for your quick response! Attached you can find the script for the import job and the resulting matlab dataset. Below you can also find the link where you can download the .bdf file. I used your e-mail address from the university of Bonn to grant you access. Please let me know whether this works, and whether you need some more information.

Thanks for sending the data; we will be looking into it.

Dear Dominik, Thank you! I noticed that the script attachments were deleted from my previous mail due to Outlook safety protocols. Hopefully the links below give you access to the intended files: C:\Users\0072494\OneDrive - Universiteit Utrecht\Documents\MATLAB\PsPM\import_bdf.m<file:///C:/Users/0072494/OneDrive%20-%20Universiteit%20Utrecht/Documents/MATLAB/PsPM/import_bdf.m> C:\Users\0072494\OneDrive - Universiteit Utrecht\Documents\MATLAB\PsPM\import_bdf_job.m<file:///C:/Users/0072494/OneDrive%20-%20Universiteit%20Utrecht/Documents/MATLAB/PsPM/import_bdf_job.m> C:\Users\0072494\OneDrive - Universiteit Utrecht\Documents\MATLAB\PsPM\pspm_part1.mat<file:///C:/Users/0072494/OneDrive%20-%20Universiteit%20Utrecht/Documents/MATLAB/PsPM/pspm_part1.mat> I also wanted to let you know that I was able to solve the 'Matrix index is out of range' error by transforming my .bdf file into an .edf file (using Brain Vision Analyzer). The issue seemed to be that the marker values had a different number of entries from the marker names. However, despite using the .edf format, the data still does not import in the right way for further processing. That is, I am still unable to trim the data using the marker values or marker names. Upon inspecting the code for the 'trim' function and comparing it to my own imported data, I noticed that the trim function refers to the marker values and names as follows: "data{k}.markerinfo.value", whereas my data can be called upon by using "data{2, 1}.markerinfo.value". My knowledge of Matlab is limited, but this seems to be suggesting that the structure of the dataset specified in the trim function does not match the way my imported data was structured. This holds for both the .bdf and the .edf data. Hopefully this information helps you locate the issue more easily. Below are the links to the .edf file and the import script: C:\Users\0072494\OneDrive - Universiteit Utrecht\Documents\MATLAB\PsPM\PsPM_course_ESCAN2024\import_edf_job.m<file:///C:/Users/0072494/OneDrive%20-%20Universiteit%20Utrecht/Documents/MATLAB/PsPM/PsPM_course_ESCAN2024/import_edf_job.m> C:\Users\0072494\OneDrive - Universiteit Utrecht\Documents\MATLAB\PsPM\PsPM_course_ESCAN2024\import_edf.m<file:///C:/Users/0072494/OneDrive%20-%20Universiteit%20Utrecht/Documents/MATLAB/PsPM/PsPM_course_ESCAN2024/import_edf.m> C:\Users\0072494\OneDrive - Universiteit Utrecht\Documents\MATLAB\PsPM\part13-edf.edf<file:///C:/Users/0072494/OneDrive%20-%20Universiteit%20Utrecht/Documents/MATLAB/PsPM/part13-edf.edf> Kind regards, Emily Emily Vanlooy (she/her) | PhD Candidate | Utrecht University | Department of Psychology | Heidelberglaan 1, 3584 CS Utrecht | Office: Langeveld G1.15 From: Dominik Bach ***@***.***> Sent: maandag 17 juni 2024 18:24 To: bachlab/PsPM ***@***.***> Cc: Vanlooy, E.A.

Hi Emily
there was a bug in using markervalues for some data types. This should be fixed in the develop branch - at the very least you should be getting a more expressive error already during import if something goes wrong. Could you perhaps try this?
Fixing the bdf import may take some more time, unfortunately.
