Data File Name:
TMS_Pred_Px (where x = participant number)
TMS_Unpred_Px (where x = participant number)

Description:
Data files separately for each participant that contain trial by trial information on exactly the stimuli and responses that occurred in this session. Raw data. 

Number of total files under extension:
TMS_Pred: 16
TMS_Unpred: 16

Number of files per participant:
1

Number of rows:
208

Number of columns:
10

ROW DATA

Row #: 1-208
Description: Each row represents one trial. There are 208 total trials. 
Data type: Each row contains the data for each trial, the column gives details of what is recorded for each trial. 

COLUMN DATA:

Column #: 1
Name: US presented 
Description: Which US was presented on each trial
Labels: 1 = goUS, 2 = nogoUS

Column #: 2
Name: Run length
Description: Run length measurement on each trial. Note the measurement is taken on the trial subsequent to the run
Labels: -5, -4, -3, -2, -1, 1, 2, 3, 4, 5
Note: 0 is presented for the first trial of every block as this does not provide a run length measure as there has not been any subsequent trials in the block

Column #: 3
Name: Block number
Description: There are different blocks of trials in this experiment in between which the participants were given a short break.
Labels: 1, 2, 3, 4, 5, 6, 7, 8

Column #: 4
Name: Planned pulse delivery
Description: Where in a trial a pulse was supposed to be delivered
Labels: 1 = during the ITI, 2 = post expectancy rating

Column #: 5
Name: Actual pulse delivery
Description: At which time point in a trial a pulse was delivered. This may vary from column #4, if a participant failed to make an expectancy rating on a pulse 2 trial. In this case a pulse would be delivered at time point 3 to ensure a pulse was delivered on each trial (i.e. when a CS finishes and the US starts) 
Labels: 1 = during the ITI, 2 = post expectancy rating, 3 = as the CS coterminates with the US

Column #: 6
Name: RT
Description: RT response made on each trial
Labels: -2 = nogoUS trial and a response was not made/required, a different negative number: an erroneous response i.e. responded when shouldn’t have, positive numbers = duration to make the correct response

Column #: 7
Name: Expectancy rating
Description: The expectancy rating made about the occurrence of the nogoUS during the CS period
Labels: Increasing scale from 1 to 9, 1 = I definitely do not think the nogoUS will be presented, 5  I do not know whether the nogoUS will be presented or not, 9  I definitely think the nogoUS will be presented. 
Note: 0 = no expectancy rating was made

Column #: 8
Name: Expectancy rating RT
Description: How long it took for the expectancy rating to made during the 5second CS period on each trial
Note: 0 = no rating was made

Column #: 9
Name: Distance from motor hotspot
Description: The recorded distance from the motor hotspot (mm) on each trial
Note: Trials on which this distance was greater than 7mm were excluded from analysis

Column #: 10
Name: Peak-to-peak MEP amplitude
Description: The peak-to-peak amplitude of the MEP on each trial recorded by Brainsight 

EXTRA NOTES
Excluded data: TMS_Pred_P9, this participant was not aware of the predictable nature of the sequence at the end of the testing session despite the instructions.
