Randomized Duration:
The duration can be specified as a range rather than a single number using a colon or semi-colon thus: 5:10 , 0;8.  In this case the duration will be set at a random value within the range, each time the column is entered.

C - Three Pulses with controlled slopes (5 seconds to 45 C, 5 seconds to 35 C)

Using the "Rate" and "Repeat" parameters.

D - "Duration" parameter special feature: negative / unspecified duration.

A negative duration means that the duration is not specified: the program will only go to the next step when a "Trigger" signal is received. A trigger option must be selected in order for this feature to work. Go to the menu "Tools/Options" to display the option window and select the desired “Trigger Source”. The default trigger source is the keyboard space bar.
Duration = -1 In this case the process switches to the next column at the first occurrence of the trigger.

Duration = -2 This feature only works for Medoc TSA's equipped with the TTL option. The control switches to the next column when the TTL level goes positive.
Duration = -3 This feature only works for Medoc TSA's equipped with the TTL option. The control switches to the next column when the TTL level goes negative.
Duration = -10 This feature was implemented for the Marstock protocol. The control switches to the next column when the trigger is detected or when the "Destination" has been reached, which ever comes first. When in Marstock mode, the amplitude reached is displayed in a text window. An asterisk is added when the "Destination" was reached before the trigger.
Duration = -11 This feature was also implemented for the Marstock protocol. When encountered, the software averages the peaks reached during the previous durations of -10 events. The total average and the average with the first and last events excluded, are then displayed in the text window. The peaks are then reset for the next series of ramps (See Marstock Mode).
This '-11' code also resets the previous data and it is recommanded to use it at the begining of a test to reset any data accidently left over from previous interrupted tests. Marstock example


E - "Destination" parameter special feature: "Hold" destination.

If the destination temperature is replaced by the word "Hold", the temperature will remain at the level it was when the step was entered. This may be useful when investigating thresholds.
When starting the program in the table below, the software waits for a first trigger signal to go from step 1 to step 2. Then the temperature increases at a rate of 1 C per second until it reaches 50 C or a second trigger signal is received. Whatever the temperature is when step 2 ends, it will be held constant during step 3. This temperature value will be displayed in step 3 "Destination" cell.

F- Remark on the "Rate" parameter.

If the "Rate" parameter  is not specified, then the maximum attainable rate is used (approximately 8C / sec for the Medoc TSA).

G - The "Delta" parameter.

This parameter permits adjustment of the destination temperature on the fly. A "Destination Delta" option must be selected in order for this feature to work.
Go to the menu "Tools/Options" to display the option window and select the desired "Destination Delta" option. The defaults are the keyboard up and down arrow keys.
If a value was entered into the "Delta" cell for a given step, the destination will be increased or decreased by this amount for each depression, respectively, of the up and down arrow keys.
Each time a "Delta" change occurs the "Destination" cell displays the new value.

H - "Jump to" parameter special feature.

When the column number specified in the "Jump to" row is negative, the jump occurs as soon as the spacebar is depressed. This feature was added to permit having a ramp or a series of steps and leave the series whenever needed by jumping to some column other than the next.

I - The "Sound" parameter.

This parameter permits selection of a sound "WAV" file to be played when control is first passed to the column.  The "Style #" must be chosen from a list accessible through the menu/Edit/Sounds shown at right.
The number to be used in the parameter table is the sequential number of the selected file in the list. This number is displayed in a small text box above the list. The complete path of the selected file is also displayed above the list.

Remarks:
  1. The Sound numbers are not likely to be compatible from computer to computer unless care is taken in making the lists in the exact same sequential order.
  2. If the "Sound Style #" is zero or left blank, there will be no sound.
  3. If the "Sound Style #" is negative or too high for the list the standard "Beep" will sound.
  4. If the sound file is not found the standard "Beep" will sound.
  5. In the case of another error, no sound will be heard.
  6. A good source of wave files is the WINDOWS/Media folder (or WINNT/Media) that can be found in most Microsoft WINDOWS based computers.

J - The "Message" parameter.

This parameter is only available when the Magnitude Estimation Device check box is checked on the option form. It permits selection of a message to be displayed to the subject monitor above the magnitude display. The "Text #" must be chosen from a list accessible through the menu/Edit/Messages shown at right.
The number to be used in the parameter table is the sequential number of the desired text in the list. This number is displayed in a small text box above the list.

Remarks:
  1. The Sound numbers are not likely to be compatible from computer to computer unless care is taken in making the lists in the exact same sequential order.
  2. The "Message" numbers are not likely to be compatible from computer to computer unless care is taken in making exactly identical lists. This can more easily be done by copying the defaults file "MessagesDefaultsOGM.txt",  that should be present in the same folder as the application.
  3. If the "Message Text #" is zero, left blank  or too high for the list, any previous message will be left unchanged.
  4. If the "Message Text #" is negative any previous message will be erased.

H - "Jump to" parameter special feature.

K - Sine Wave Generation.

As shown in the two examples below, a half cycle sine wave is generated when the "Rate" parameter is set to a negative number.  The "Duration" parameter determines the period of the sine wave ("Duration" =  Period / 2), and the difference between the current stimulus and the "Destination" determines the Amplitude ( The absolute value of the difference = 2 x Amplitude of the sine wave).
