22: Brain Data viewer and Export Brain Data

Use for to see Brain Data dictionary format files and for save this files.

Not good for long time data.

22 B: Select Tools / Export Brain Data...

Use for only save Export Brain Data. Can not see actual data iinside this window.

Good for long time data export and easy to open by application like Excel.

22 A: Select Tools / Brain Data Viewer and Export

22 A.1: select IBVA4 dictionary with "Preference/PreSet"

In the "Preference/PreSet" window, select IBVA4 data dictionary in the "Save Preference Setup" information which you like to see or export.

Then Open "Tools/Brain Data viewer & Export" window.

Click "IBVA4 Brain Note" Line to show data.

22 A.2: recommend to use this function less than 10 min. long data.

Data will show start time Zero to current time in this window.

It's too big to show long time recording data.

About 10 min is 1 MB size text file is ok to see this way.

You can set 'Start point" to change time X, then time X to current time will show in this window.

Need to set Time and Data dictionary this before open this window.

Or need to close window then open again for new data setup.

* In case select Brain Data CH 1, 2, 3, 4, text data size is very big. Take time to show in the Brain Date Viewer window.

Click "Save data", then see that data is more easy way. This export file can open by any Text editor application.

22 B: Select Tools / Export Brain Data...

22 B.1: use for only save Export Brain Data. can not see actual data in this window.

22 B.2: Export Data range.

Set Title, Start Time and End Time to Export.

22 B.3: Export Data type.

Select Export Data type.
