External Email - Use Caution
Dear All,
I hope you are fine and in good health,
I am starting a new project, and I would like to use MNE,
I would like to compare OPM-MEG to SQUID MEG,
I know mne from past, but this is the first time that I want to install it and use it,
I saw that mne deal with OPM like:
https://mne.tools/dev/auto_examples/time_frequency/plot_source_power_spectrum_opm.html
I have some questions and thank you for your answering:
1) I would like to know if is possible to access the data, for example to look about how the OPM sensors are oriented,
in the script you put: subject<https://docs.python.org/3/library/stdtypes.html#str> = 'OPM_sample' so does it mean the sample data are accessable?
it is possible to get the lead field matrix? sorry if it is simple question because
I try to install the mne to see what the script should give but when I run it I have some errors, so the second question:
2) I installed anaconda version 3.7 and pycharm and I follow this link:
https://mne.tools/stable/install/mne_python.html
I run an example from mne, I get the below error:
C:\Users\zahransa\anaconda3\python.exe C:/Users/zahransa/PycharmProjects/opm/plot_opm_data.py
