Configuring Epilepsy Analysis

After installing and configuring the analysis machine: https://megcore.nih.gov/index.php/Configuring_analysis_machine

Configuring Data Editor Layout

Configurations are stored in the ChannelSet.cfg file. Current Montages Include:

• MEG_LCR_22
• MEG_LCR_22_EEG_LCR_21
• EEG_

Creating a View Montage

The data editor layout orders the channels by acquisition order and may not be preferred
To create ordered channels, a virtual channel dataset will need to be created

 DataEditor >> Edit >> Virtual Channels
 Select a virtual channel and add to Plus Box >> Name the new channel (it must be different from acquisition names - choose lowercase or uppercase as a workaround)
 Save the virtual channel .vg file to $HOME/.meg/resources/default.vg
 

Head Model

 MRIConvert   >> imports mri into ctf format
 MRIViewer -mri CTF.mri >> creates headshape and headmodel >> save to default.hdm
 Dipolefit -hdm default.hdm

Dipole Fit

 Set the time, epoch, and duration of dipole fit
 Possibly better to set latencies for fits and run through the commandline dipole fit

Processing Pipeline

check tags >> cat anat+ortho.HEAD | grep TAGSET_LABELS 3dtagalign << avghc.py << creates an average head position changeHeadPos << rewrites the head position
