Function Reference

MEG Raw Data

• Raw_BrainArea: Calculate the fiff data and save the raw data into different brain areas in matlab format

• Raw_fifftomat: Read data in fiff format and convert them into Matlab data format

• ref_trigger_read: Read the trigger information from a task (in fiff format)

• fiff_setup_read_raw: Read information about raw fiff data and set up for segment

• fiff_read_raw_segment: Read the specific raw fiff data segment and convert them into Matlab data format

Threshold

• GetAveThre: Get the average threshold in all task of one subject

• GetTriggerTime: Read the triggers in each task

• GetEachThre: Get the threshold in each task

Frequency

• GetAllRawFreq: Filter the raw data to five frequency bands (Gamma, Beta, Alpha, Theta, and Delta)

• GetFreq: Filter the raw data to a specific frequency band

Granger Causality

• GC_Evoked: Set up the data for moving window calculation for Granger causality multichannel model

• Regress_window: Compute the Granger causality from the moving window multichannel models

• AICBIC: Compute AIC and BIC to determine the best order for Granger causality modeling

Figure

• GC_ConnPlot: Plot GC connections among different channels and regions

• GetConnfig: Create and save the dynamic connection figures through the time of the task for each subject

• MakeMovie: Create the video file (AVI) of the dynamic connection between different brain areas for each subject
