going off the error message, are the data, info and label files there alongside the .cef file?

I am trying with only one cef file and it is requesting hpi file. In the first place, aren't labels needed unless process them in an annotation function? The cef file contains only number list values.

yes, this is what the error message is trying to tell you. I think the "read_raw_curry" function tries to find the "sidecar" files that contain the labels and such automatically, cannot find them, and hence gives this error. These files probably need to be in the same folder as the .cef file
