Question about "Pcap2matlab_example.m"

[AlexMCD-bot]

Hello, I am sorry to bother you. I am working on your program "pcap2matlab", and I found it extremely suitable for my research area. However, when I ran the program "pcap2matlab_example.m", I met with the following problem,

---

Index exceeds the number of array elements
(0).

Error in nestedSortStruct (line 63)
fieldEntry =
aStruct(1).(fieldNamesCell{ii});

Error in pcap2matlab_example (line 39)
pcap_result =
nestedSortStruct(pcap_result(packet_format ~=
PKT_WITH_ERROR),...

It would be my greatest pleasure if you can anwser this question for me when you are free.

Best regards,

Hello and thank you for your interest in this library! Unfortunately I no longer have access to MATLAB, so there's no way for me to debug this. Moreover, there's a lot of information missing in your question, to be able to reproduce the problem, for example: 1) MATLAB version 2) Python version 3) Wireshark version 4) OS I guess I should mark this utility as "archived".

Thank you so much for responding so soon! The missed information are as follows,

1. MATLAB R2020a
2. python 2.7.17
3. wireshark version 3.0.1 (v3.0.1-0-gea351cd8)
4. window 11

Thanks again for your kindness!
best regards,
Cong

@AlexMCD-bot Now that I think about it, did you try running pyshark_example.m? This is a newer example that addresses various issues I ran into with pcap2matlab_example.m and didn't know how to solve. If no - before you do that, make sure you have v0.3.8 of pyshark installed (this is the last version supported on python 2.7).

Just to clarify - you still get the same outputs in MATLAB, it just uses python in the background.
