(Help
> Defining New user)
o
When MovAlyzeR is started, the User Management screen will
appear, displaying existing users. If you are using MovAlyzeR
for the first time or if you have yet defined any users,
only a Default user UU1-NS Example 1 is listed.
o
UU1 is provided as an example user with some experiments,
with the default user root path "C:\Program Files\Neuroscript\Movalyzer\Examples".
The experiment and data files are stored in this folder.
o
Create a new user by clicking '+'
User
o
Type in a three letter user ID and description.
o
Click on Change Password to select a
password for the User. The default password is
userpass. This password allows the User to define,
view or change confidential data that identify subjects.
Settings
o
Set the Root data path
The default root directory for the User is:
C:\Program Files\NeuroScript\MovAlyzeR\<UserID>
The default backup directory for the User is:
C:\Program Files\NeuroScript\MovAlyzeR\<UserID>\BACKUP
These
locations and paths may be modified; however, it is recommended
not to use “c:\program files” as a root directory
for your data, but instead use an easily identifiable directory
on your local disk, with write permission. The user needs
write permission in the user's root data path to be able
to process data. If a user has no write permission, please
use a newly defined user's root path with the proper write
permission.
When
uninstalling Movalyzer, the user's data will NOT be disturbed.
Input
device
o
Select input device: Choose the input device
you want to use to make a recording/collect data.
By
default, the Recording device is a mouse.
Digitizer
tablet (install wintab - see
help on wintab installation). The option 'tablet' is
enabled only if the tablet driver is installed.
DAQPad
(Gripper device): The option 'DAQPad' is enabled only if
the National Instruments DAQPad driver has been installed.
(see help on gripper
installation). This option is available only in the
comprehensive MovAlyzeR package (as in trial version), or
GripAlyzeR package.
o
Set Mapping preferences (for digitizer/mouse):
You can map the recording to the entire desktop or just
to the recording window area.
If
you are using a mouse, specify the desktop screen width
and height.
If you are using a tablet as the recording device, in
addition to desktop screen dimensions specify the dimensions
of your tablet.
o
Click 'OK' and a new user with the specified
user ID is created.
o
Choose the user and click 'Select'

Mouse:
o
Verify that in Settings (from main menu) > Select input
device, the input device is chosen as mouse.
o
Settings (from main menu) > Test/Record input device
> 'Test device free-hand' > GO.
o
Move the mouse inside the recording window, while keeping
the left click key pressed. Note down the sampling frequency
(Equal to Timer call and position update, which should be
equal).
o
After the recording, a chart will be displayed with the
raw data.
Tablet:
Repeat
the above procedure with input device selected as tablet.
To record movements, using the tablet, move the pen on the
tablet with the cursor on the recording window. Note down
the sampling frequency (Equal to Timer call and position
update, which should be equal).
o
Few seconds after the movement stops, a chart is displayed
with the raw data.
Gripper
or other analog device: Repeat the above procedure with
input device selected as DAQPad. To record movements, using
the gripper, place the upper and lower grip units on the
table. Then place the left and right thumbs on the upper
and lower grip sensor plates and apply uniform pressure.
And pull the upper and lower units apart.

(Help
> Experiment Settings)
The
experiment settings contain settings specific to run and
process a particular experiment. This information should
be the same for the entire experiment and should be stored
with the experiment and should not change

Right Click on Experiment E01 > Experiment Settings
Recording:
Procedure
o
You may check the option, 'Delay erasing recording window
until ENTER Key is pressed'. This option allows the recording
pause after every trial until the enter key is pressed.
(E.g, while using the gripper)
Recording:
Input Device Settings
The
input device settings contain settings specific for operating
the device to collect data.
Note:
After setting both input device settings and experimental
settings, each of the experiment settings needs to be verified
in a trial of processed data.
o
Update the Sampling Rate as reported by the system (visible
in the upper left corner of the recording window during
the test of mouse or tablet). Use the
scan rate when using the DAQPad.
o
Specify the Minimum Pen Pressure and Resolution of the device
you are using. To get optimum results, you need to specify
the correct resolution for the device you are using. For
information on how to arrive at the pen pressure and resolution,
refer the specific
help topic.
o
Click 'Reset Defaults' if you want to work
with the default settings instead.
o
Click 'OK'
o
NOTE: Everytime you change input device, it is necessary
that you change the input device settings per experiment
before recording or processing the trials (Eg. from mouse
to tablet), in order to obtain the correct results.
DAQPad
Settings: If you are using a gripper device, in
addition to experiment settings described above, change
DAQPad Settings (enabled only if input device is selected
as DAQPad)
o
Use the DAQPad to record movements from devices that required
analog to digital conversion. E.g., Gripper, force sensor,
turn pot meter.
o
To view/change the DAQPad settings, go to the MovAlyzer
Main toolbar > Settings > Select input device >
DAQPad settings. Use the settings that came with the specific
analog device.
o
Choose the options 'Report in Newtons' and 'Double Buffer
mode' with 'Samples' as 20, for real-time feedback.
