SD card Sampling rate and OpenBCI GUI v4.2.0
I'm using Cyton Daisy with SD card for collecting EEG data. The sampling rate mentioned on website is 250hz, however, my data is being sampled at 256hz, as shown in this images:
Is it okay to have this minor difference?
Also, in order to convert the hex valued .txt file stored on sd card, I'm using OpenBCI GUI v4.2.0 which has inbuilt option to convert the sd card file. Is it a good way to convert sd card files for now?
