I want to use the data from the emotiv but I need its values in Voltage.
I've read the documentation thoroughly and I've found myself with a question. What's the difference between the data written by having write_decrypted and write_values set as True?
If write_values is set as true it writes the sensor and quality values and saves them to a 'emotivvalues*.csv' file, of which I've obtained the following data:

However, if write_decrypted is set as True, it says that it writes the data received after decrypting it. And then saves this data to a 'emokitdata*.csv' file.
How is this decrypted data different from the sensor values and quality values? Given that I obtain something similar to this when write_decrypted is enabled:

So, to recap, I'd like to know the difference between these two options.
As of now, I've assumed that the 'emotivvalues*.csv' file was the correct one since I can somewhat make sense of it if I substract 4096 from it and multiply it by 0.51 according to the resolution and LSB value of the emotiv. Am I correct in this assumption?
I want to use the data from the emotiv but I need its values in Voltage.
