Dear Aravind, You can do any tutorial in any order, but as a beginner it is better to do it in order. The spectrometer tutorial should be able to work for a 14 bit board, but if you go through the steps you will see that the spectrometer bit growth is based on an input of 10 bits. You would need to change that based on an input of 14 bits. The python script would also need to be updated to handle 14 bits or so I think. This could be why you are experiencing these issues reading back from the snapshots.
I would have to see your script and your slx file that you have updated in order to see if they are correct. Send that to me and I will glance over it.
