i2mc feature extraction error via MATLAB #4

Open MdShadmanHasan opened 1 year ago

MdShadmanHasan commented 1 year ago

After properly formatting my data according to the internal data format used by irf, when I run the MATLAB script to extract the i2mc feature I get the following error.

nfile =

Error message says "Data length must be larger than 24 samples". Is your data longer than 24 samples?

MdShadmanHasan commented 1 year ago

Yes! The array has 45978 samples!

Well, then the only thing that I can suggest is: try to run training/testing using the data provided in this repository, and compare if your .mat file has the same format as files you get when replicating results
