Nueral response prediction error

[shanggao11]

Hi there!
May I ask a question about the neural response prediction part?
I have a neural response array in firing rate (FRarray)along with camera stamps and neural stamps; both camera stamps(CSarray) and neural stamps(NSarray) are in frames. NSarray.shape==FRarray.shape(if ignore the number of neurons); CSarray.shape match with the input video frames (I input a 5 mins data, but the facemap only read in 4.2 mins data, I tried both the size of 5 and 4.2 mins); It gave me this error when I run the neural response prediction, Please help me about this, thank you very much!:

Hi @shanggao11 can you please confirm if you also load the camera and neural stamps when you run the prediction?

Thanks for your reply! yes,i am sure that I load the camera and neural stamps.
