Questions about PPG data
I have a few questions about the PPG data. 1) In the streaming data, I see 4 values: what are they, in order? There's three in the csv: IR, RED, and Ambient 2) In your experience, when there is a good fit, what is the typical range of IR and RED? When I graph the values, I see peaks of RED around 60...

Streaming PPG data
is it possible to stream PPG data? I tried looking at the wrong output from dispatcher and looking at the settings, but I didn’t see a way to do this. i’d ideally like to be able to stream data related to heart rate.
Thanks for all the help, and being so responsive to my questions!

Raw EEG output after filtering
I'm trying to display raw EEG output from Mind-Monitor in a way that could be assessed by standard visual inspection. Here's what I've done: Normal EEG range is between 30-150 Microvolts. Muse picks up a lot of ambient signal and has a range in +800 MV. I emailed the developers at Interaxon and was ...

Re: Recommendation for microvolt conversion
The definitions of microvolts for different sleep stages is in that range. Most sleep stages have a uV less than 150 microvolts https://emedicine.medscape.com/article/1140322-overview#a3 I tried posting on Muse direct developer website and no one got back to me. The Muse ranges just aren’t compatibl...

Re: PPG information of Muse-2 and Muse-S in Muse Monitor
@james, I'm having trouble finding the PPG data in the recorded file. I recorded a large session on an Android device and then uploaded the raw file to a Pandas dataframe. Here are all of the columns present. Mellow and concentration are present, so I think I enabled the extra variables correctly by...

Re: Recommendation for microvolt conversion
I’m still confused and could use some advice then. i’m using a python package that seems be to measuring raw EEG signal in the 50-100 range. I read that this was more typical. In this python notebook detecting slow wave sleep patterns (below, (what i believe is) the raw signal has a uV value much lo...

Recommendation for microvolt conversion
Is there a recommended way to convert the raw microvolt values into the 0-100 range? I'm reading that RAW eeg microvolts are usually in the range of 0-100, but the measures from mind-monitor/interaxon are much higher. https://www.learningeeg.com/terminology-and-waveforms I tried reading on the other...

streaming to url
Is it possible to stream mind-monitor to an external URL? I want to create a server side application that accepts streaming data directly from the app and responds with biofeedback signals (like tones). And, if this is possible, do you forsee any issues, like lag? I'd be ok with anything that doesn'...

What is the best way to save files that are several gigs large? I need to do sleep recording at a constant rate for over six hours. I’m worried about losing the files or waiting for them to upload automatically to dropbox. I record these on my phone. If i navigate to a different app (or the app is i...
