Hello, sorry for not responding on the last post, its been really hectic on my end. I did what you said, but still get an similar error.

UPDATE 4/11/17 I have now fixed this problem by installing pyserial. I seem to have another problem now. After reading the data from rest position and first finger, the connection between Bluetooth and myo band seems to disconnect and it will stop recording the data. There is no error message. Also as soon as I remove the Bluetooth dongle an error message pops up. This is weird because there is no light on the myo band, saying that it is connected.

UPDATE 4/12/17 I figured out how to go around the problem by using my other computer. But now when I run the third program it gives me this error message import pywt; ImportError: No module named pywt thanks

Hello, in your last case pywt is a library related with the Wavelet transforms. So you can install it by using pip. in iPython console you can type: "!pip install pywt" or "!pip install PyWavelets" without using "

Hi, thanks that worked. I actually got to the end of the process, but the analysis on which finger was moving was not very accurate. Is there a certain teqnique/way I should be recording the data, thanks.

It is good to hear you achieve to work with code :)
You can try to classify different hand postures. For example, instead of the finger movements, the default 4 movement (fist, finger spread,wave in, wave out) of the myo armband can easily be classified using my code. But some of the other movement cannot be exact as that much. The input signal can be effected various things like human skin, muscle intencity, tiredness... To classify the finger movements, while i was doing movement, i touched to my palm with the my fingertip. So mostly it worked for me, you can also try it but we can not be sure. Can you share with me the result of the your experiment? (will it works or not?)

According the code, it can classify the movements using their wavelet transforms as feature of the signal and NN as a classification algorithm. I am still working on to develop more accurate algorithms. Best regards.
