spikes in MUSE data when preprocessed in EEGLAB

[daga3467]

thanks for the help. I guess data analysis of raw data best conducted in EEGLAB rather than relying on output for analysis direct from the csv files into say SPSS (or even just in excel)

Filtered out elements in csv results now in an error message (it basically doesn't like it when the csv is edited and saved prior to importing into EEGLAB)

How did you edit it? If you edit it in Excel, Excel will change the timestamp format of the first column.

[daga3467]

yes it was in excel, is there anything i can do to offset the issue using excel?

[James]

You need to set the timestamp format to preserve it as "Year-Month-Day Hour:Minute:Second.Microsecond"

The RAW EEG in the CSV is unfiltered.
The brainwaves have blink artefact removal and power line noise removal that is done in Interaxon's closed source code, so I can't tell you exactly what's been done, only that it is.

May I ask if you mean that the raw eeg data provided by mind monitor is the EEG data of wink artifact elimination and power frequency interference elimination done by interaxon? Does interaxon do high and low frequency filtering? Or does mind monitor provide the function of high and low frequency filtering?

All brainwave filtering is done by Interaxon's code. RAW EEG is unprocessed.
