- Method Detail
  - getCode
```
public java.lang.String getCode()
```
    Returns the code associated with this sequence of trials. The code is the string assigned to the sequence to associate text conditions (e.g., participant code, device code, etc.) with the sequence.
  - getThroughput
```
public float getThroughput()
```
    Returns the Throughput for the sequence of trials.
  - getMT
```
public float getMT()
```
    Returns the mean movement time (ms) for the sequence of trials.
  - getNumberOfTrials
```
public int getNumberOfTrials()
```
    Returns the number of trials in this sequence.
  - getTaskType
```
public int getTaskType()
```
    Returns the task type for this sequence. The return value is the int given to the Throughput object (via the constructor of setData). Should be Throughput.ONE_DIMENSIONAL or Throughout.TWO_DIMENSIONAL.
  - getTaskTypeString
```
public java.lang.String getTaskTypeString(int taskType)
```
    Returns a string representing the task type for this sequence. The string returned is "1D", "2D", or "?" (if the task type is unknown).
  - getResponseType
```
public int getResponseType()
```
    Returns the response type for this sequence. The value returned is the int constant passed to the Throughput object in the first place (via the constructor or setData). Should be Throughput.SERIAL or Throughput.DISCRETE.
  - getResponseTypeString
```
public java.lang.String getResponseTypeString(int responseType)
```
    Returns a string representing the response type for this sequence. The string returned is "Serial", "Discrete", of "?" (if the response type is unknown).
  - getFrom
```
public android.graphics.PointF[] getFrom()
```
    Returns a point array containing the "from" points for the trials in this sequence. The "from" points are the coordinates of the center of the target from which each trial begins.
  - getTo
```
public android.graphics.PointF[] getTo()
```
    Returns a point array containing the "to" points for the trials in this sequence. The "to" points are the coordinates of the center of the target to which each trial proceeds.
  - getSelect
```
public android.graphics.PointF[] getSelect()
```
    Returns a point array containing the "select" points for the trials in this sequence. The "select" points are the coordinates of the point of selection where each trial terminated.
  - getMTArray
```
public float[] getMTArray()
```
    Returns the float array holding the mt (movement time) values for the trials in this sequence.
  - getSDx
```
public float getSDx()
```
    Returns the standard deviation in the selection coordinates for this sequence of trials. The coordinates are projected onto the task axis.
  - getX
```
public float getX()
```
    Returns the mean of the selection coordinates for this sequence of trials. The coordinates are projected onto the task axis.
  - getDeltaX
```
public float[] getDeltaX()
```
    Returns the array of selection coordinates for this sequence of trials. The coordinates are projected onto the task axis.
  - getA
```
public float getA()
```
    Returns the specified amplitude for the trials in this sequence. NOTE: This value is not used in calculating Throughput. It is provided only as a convenience.
  - getAe
```
public float getAe()
```
    Returns the effective amplitude for the trials in this sequence. The effective amplitude is the mean of the actual movement amplitudes for the sequence of trials, as projected on the task axis.
  - getW
```
public float getW()
```
    Returns the specified target width for this sequence of trials. NOTE: This value is not used in calculating Throughput. It is provided only as a convenience.
  - getWe
```
public float getWe()
```
    Returns the effective target width for this sequence of trials. The effective target width is 4.133 x SDx, where SDx is the standard deviation in the selection coordinates, as projected onto the task axis.
  - getID
```
public float getID()
```
    Returns the specified index of difficulty for this sequence of trials. The specified index of difficulty is ID = log2(A/W + 1). NOTE: This value is not used in calculating Throughput. It is provided only as a convenience.
  - getIDe
```
public float getIDe()
```
    Returns the effective index of difficulty for this sequence of trials. The effective index of difficulty, IDe = log2(Ae/We + 1).
  - getMisses
```
public int getMisses()
```
    Returns the number of misses for this sequence.
  - getErrorRate
```
public float getErrorRate()
```
    Returns the error rate as a percentage.
