readgenbin

Usage:
[data, time_trace] = readgenbin(filename, start_time, end_time, endian);

Parameters:
filename: Path to GENESIS file.
start_time, end_time: Time in milliseconds relative to the ACTUAL
time of the experiment at which data adquisition started
(if you start gathering data at 200 ms and you specify 0
start time it will not work). If either is [] or NaN, defaults
to beginning and end of trace, respectively. end_time is
not inclusive.
endian: (optional) Indicates file format; 'l' for little endian
and 'b' for big endian. See the "machineformat" option
in fopen for more information. Defaults to the native endian
of this computer.

Returns:
data: Data vector or matrix read.
time_trace: (Optional) Corresponding time range vector (in ms).

Description:
Files should be created by the disk_out method in the GENESIS neural
simulator. No checking for binary type is made, so if you want reliability please
ensure the file is a binary. Files written by GENESIS on big-endian
machines (like old Mac and Solaris machines with PowerPC architecture)
must be loaded with the endian='b' option. There are sanity checks to
flag that the file may be reverse-endian, but this is not automatically
corrected.

Example:
Fully read a native-endian file:
>> dat = readgenbin('mydir/myfile.bin');
Specify a time range:
>> dat = readgenbin('mydir/myfile.bin', 100, 1000);
Get a time vector back:
>> [dat, t] = readgenbin('mydir/myfile.bin', 100, 1000);
>> figure; plot(t, dat);
Force to fully load big-endian Mac file on PC platform:
>> dat = readgenbin('mydir/mymacfile.bin', NaN, NaN, 'b');
