Neuroscore's ZDB files are just SQLite 3 databases with an '.zdb' file extension.
SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is the most widely deployed SQL database engine in the world. The source code for SQLite is in the public domain.
##From the command line
This repository includes a python script zdb.py, which provides the ability to modify ZDB files from the command line. This script can be invoked by:
python ./zdb.py [optional arguments]
###install
To run the script without calling python every time, run the following command (if you're on a unix-like system):
sudo chmod 755 zdb.py
This changes the permission of the script to 'executable'. You can now run it as:
./zdb.py [optional arguments]
###usage
The full command-line arguments are:
./zdb.py [-h] [-zdb ZDBFILE] [-txt TXTFILE]
The -h switch will display a help menu about basic command-line usage to the zdb script.
###adding a sleep score from a TXT
The sleep score column from a TXT file can be merged with a ZDB. To add a sleep score from a TXT file, use the following syntax when calling zdb.py.
./zdb.py -zdb ZDBFILE.zdb -txt TXTFILE
where 'ZDBFILE.zdb' is the name/path of a ZDB file. Likewise 'TXTFILE.txt' is the name of a TXT file.
##from Matlab
This repository provides Matlab wrappers around some basic functions of SQLite 3's C API. This allows you to execute SQLite queries on an embedded database.
###install
On Windows, you will probably need MinGW32 or Cygwin to install. Use GNU Make (or mingw32-make).
On OSX use iff build to compile; the program iff can be found at elseiff.com.
###usage
The Matlab API exposes 2 mex functions zdb_get_score, zdb_set_score.
% full path to a zdb file
file = '/path/to/neuroscore.zdb';
% retrieve all the scores in the file
scores = zdb_get_score( file );
% modify a score
scores(5) = 'W';
% update the ZDB with the modified data
zdb_set_score( file, scores );
