Tweak and optimize current source localization analysis pipelines of OPM data for oddball task

[hzaatiti-NYU]

• Fix any problem with the coregistration scripts of OPM data
• Define trials, averaging
• Perform beamformer in time-lock analysis and frequency analysis
• Tweak all the parameters of the pipeline to obtain the best results

Today I met online with Hadi. The topics discussed:

1. To improve the coregistration of the MRI with the Polhemus laser scan we need to define with 3 anatomical points (NAS, LPA, RPA). To define these points in the MRI scan we can use Vitamin E earplugs during the MRI scan that give high contract in the T1 image: https://www.proplugs.com/c-74-proplugs.aspx
2. Potentially, we will work in the future on a median nerve stimulation experiment.

My tasks:

• [x] Sensor-level analysis
• [x] Co-registration MRI and headshape
• [x] Co-registration OPM sensors and headshape
• [x] Source-level analysis: dipole fitting

This task is finished. Possible things we can work on in the future:

• Denoise with homogeneous field correction
• Beamformer timelock analysis
• Group analysis: Averaging source results in MNI brain.
