Hi, I am new to Matlab and Ledalab. And I'm trying to analyse some CDA data. I import the data into Leda as a txt file (like example in attachments). I can import the data success. However, when I try to do CDA, it doesn't work. I'm not sure what to do. I've attached the files . If anyone has any ideas or tips how to solve this, please let me know~ Best
