Using EEG Electrode Cap Starter Kit for Brain Mapping to study impacts of entheogenic experience

Hi everyone,
I'd like to use the OpenBCI EEG Starter Kit in conjunction with the NewMind software to do qEEG brain maps before and after entheogenic experiences.
I'm curious if anyone has used the data from the OpenBCI starter kit in conjunction with NewMind. I know you can go from CSV to EDF but interested to find out if anyone used both of these together (OpenBCI and NewMind).
Also is there a reason why the starter kit doesn't do linked ears montage?
I'm still new to this space and trying to understand the differences in configuration.
And are there ways to determine signal quality compared to the hardware I would get from NewMind for example.
Thank you.

    Just ignore that reply. I put it in original message and can't figure out how to delete my reply.

    Hi Sebastien,

    I've used the NewMind system in the past with the Brainmaster Discovery 19 channel amp. And also with the previous 'MiniQ' based (2 or 4 channels at a time) older approach. I have NOT used OpenBCI with NewMind.

    As you might know, most QEEG work is done with amps that have gone through a 'calibration' process. This is the case with Discovery, and likely also the case with the 19 channel amps that NewMind now sells. So there currently is no QEEG calibration phase available with OpenBCI gear. Additionally there are other differences: 16 channels vs 19 channels, 125 Hz sample rate vs 256 Hz, etc.

    So I would be hesitant in assuming you could do NewMind QEEG with 16 channel Cyton+Daisy. There is much more involved than just getting the data into EDF format.

    Maybe it's possible for you to work directly with Richard Soutar and his tech team to surmount those issues? But would they do that to undercut their own hardware?

    Thanks William, this is very helpful. I appreciate it. And I don't really want to put them in a position that undercuts their own hardware. It's just out of my price range right now and I was looking for a solution that maybe involved a bit more hacking but was more within reach.

    I believe the hardest aspect would be the channel count difference, and sample rate differences. QEEG databases are designed to work with standardized elements of 19 channels and 256 Hz sample rate. This would be challenging (if even possible) to convert.

    re: NewMind 19 channel amp being 'older tech' ?

    I'm not sure how you determined that, but Richard is very exacting in his specifications. I'm sure his gear is as good as Brainmaster's. So another route you might consider is looking for used Discovery amps, or other 19 channel gear that NewMind talks to.

    Regards,

    Super helpful. Thank you Williams. Great pointers. I also removed my perspective on the age of hardware, given I am in no way an expert and I actually was super impressed with many aspects of NewMind.

    Here is a related thread on potential open source QEEG databases. Not that any currently exist, but may in the future.
