Experiment Conditions
This is a common topic for MovALyzeR, GripAlyzeR & ScriptAlyzeR. These programs will be referred to as MovAlyzeR on this page.
* How to: Create/add a new condition, remove a condition, duplicating a condition

* Trial Replications per condition
After creating a new experiment the particular experiment shows the Groups and Conditions headings, otherwise double click Experiments.
When creating new conditions or editing existing conditions, they will be added to a master list, and can be used for future experiments. This assures consistency of a user's database. For example, in the window below, the conditions CCC and DDD appear both under the experiment and in the Master 'conditions' list.
o To create new condition and add the conditions to an Experiment
o Right click on the experiment >Add Condition(s).
o The 'Add conditions' window will appear as follows:
o Option 1: Pick an existing condition in the list (e.g., 'LPP') by clicking on the ID and click 'add'.
~ NOTE: Previously added conditions will not appear on the list, but are still in the master list.
o Option 2: Add a new condition to the master list by clicking the + button.
~ Set the necessary properties as described in the following sections: General, Stimuli, Stroke description and word extraction and click OK. The condition will be added to the master list.
~ NOTE: Alternatively, fill in the general information and click OK. You can add the other properties by right-clicking the condition > condition properties later.
~ Select the condition(s) to be added and click add.
o The other tasks that could be done in this window are: 1) Remove a condition from the master list: click the 'X' button, 2) Check the condition properies: click the hand button, 3) View relationships : click the tree button.o To remove a condition from an experiment
o Go to the Experiment (e.g., EEE) and expand the tree by clicking '+' buttons. Experiment conditions (EEE conditions), right click > Remove from experiment.
~NOTE: The condition will be in the master list to make it available for the current EEE experiment or other experiments for the user.
o To permanently remove the condition, navigate to master list of the conditions, right click > delete..
o To permanently remove the condition you can also right click on the experiment > add conditions > select the condition > click the 'X' button.
o Duplicating an existing condition
o Go to the condition you want to duplicate by either expanding the experiment tree and looking under experiment conditions or go to the master list of conditions.
o Right click on the condition > Duplicate.
o All the properties are retained except the three letter ID. Change the three letter ID, alter any properties you want, and click 'OK'.
o The condition is then added to the master list, not to the experiment. You can then add it to any experiment as described above.
o This option is extremely useful to create a number of similar conditions without having to enter all the information repeatedly.
Trial Replications per condition
Properties per experiment condition (condition added to an experiment):
o The number of trial replications of a particular condition can be chosen per experiment.
o Double click a particular experiment > Double click conditions > Right click a particular condition > Click Trial Replications.
o Never collect only 1 trial. The absolute minimum is 2 trials. Accuracy improves linearly with 4, 8, 16, 32, ... trials. Since trials may fail the consistency test, it is recommended to collect at least 6 trials.
o NOTE: Since the number of trials are specific to an experiment, when the same condition is used in different experiments, you cannot set the number of trial replications for a condition in the Master list.
