data dict

Global var [scannerdata]

• Attributes of each trial: 
• [iArtifacts]: if the current trial is considered as a "bad" trial due to artifacts, ∈ (0: good trial; 1: bad)
• [iTrialType]: trial type {1,2,3,4,-1}
• [iInstructionLength]: length of the instruction period, ∈(100:1000 ms), source: presentation log 5xxx.
• [iOffIndex]: the block index number for current trials's light off in eegData02, ∈(1:191)
• [iOffOffset]: the offset index number for current trials's light off  in each block in eegData02, ∈ (1:12500)
• [iOnIndex]: the block index number for current trials's light on in eegData02, ∈(1:191)
• [iOnOffset]: the offset index number for current trials's light on  in each block in eegData02, ∈ (1:12500)
• Attributes with respect to the raw markers (markerData(1, x).trial & time)
• [lightOnTimeClean]: clean events of light on events (with double trigger events manually removed)
• [lightOnCleanIndex]: index of clean events in the originally markers -- gData.markerData(1,1).trial
• [lightOffTimeClean]: clean events of light off events (with double trigger events manually removed)
• [lightOffCleanIndex]: index of clean events in the originally markers -- gData.markerData(1,2).trial
• EEG channel working data
• [eegData02]: EEG working data. {Column 1: left&Right. Column2: up&down. Column3: info channel}
• Column3 info channel data format: [condition].[iTrialtype]  e.g. 54.1 = light off for proleft, 52.3 = light on for antileft
