HOW DO I INSTALL SETIEASY?
**************************

There is an online users guide for v1.33 at
http://asrg.contactincontext.org/setieasy/v133_user_guide.htm

IF YOU DOWNLOADED A .ZIP FILE, UNZIP IT:

   Unzip the file using a unzip utility like WinZip or EZip.

 
Put the setieasy_v133.exe file in a directory with the radiotelescope data file to be analyzed.
NOTE TO USERS OF OLD VERSIONS: The input files can be WAV format. You do NOT need to convert
them with Goldwave.

**********************
HOW DO I RUN SETIEASY?
**********************
Enter the directory folder into which Setieasy was installed.  Double-click on the setieasy_v133.exe icon
to run the program.

It can take several hours for setieasy to run on a data file, and many minutes before any output is
produced after beginning to model the data.

Post a signal report on the discussion group at http://asrg.contactincontext.org/seti/datafiles.html 
if a flag appears at the end of a file:
"UNUSUAL SIGNAL DETECTED BY SETIEASY V1.33".  
The flag message does not indicate an extraterrestrial signal has
been received.  Rather, the message indicates only that a particular data block has a noise
distribution slightly different from the noise distribution of the first data block of the same
size in the file.  Others will conduct further analyses to establish the nature of the differences
in the noise distributions, and notify you of the result on the discussion group.

NEW FEATURES:

v1.33 counts the unusual signals at the end of the log file.

The dechirped file is provided as output and each dechirp factor is put into separate log files and graph files. 

For example, using the cammand line            
setieasy_v133.exe linear_drift_1.wav linear_drift_2.wav out.txt graph.txt 0.5 -0.5

    in a batch file, the output files will be: 

    D0.5_linear_drift_1.wav, D0.5_linear_drift_1.wav, D0.5_out.txt, D0.5_graph.txt 
    D-0.5_linear_drift_1.wav, D-0.5_linear_drift_1.wav, D-0.5_out.txt, D-0.5_graph.txt

LIMITATIONS:

The 2 input wav files have to be the same duration (in minutes or hours).

The 2 input wav files have to be the same bit size (both 8-bit or both 16-bit).

The dechirp factors provided have to be in the range of [-1,1].

No more than 300 dechirp factors can be provided as parameters (for batch files).

******************************************
USING A BATCH FILE FOR BULK ANALYSIS
******************************************
USING A BATCH FILE FOR ANALYSIS OF MULTIPLE FILES

In Windows, you can write a batch file to make SETEasy v1.33 analyze several files with only one command
from the user. The first line in a batch file is '@ECHO OFF'. The following lines are commands that would
normally be typed on a dos prompt.

For example:


@ECHO OFF
setieasy_v133.exe linear_drift_1 linear_drift_2 out.txt graph.txt 0.05 -0.05 0.15 -0.15 0.41 -0.41
setieasy_v133.exe linear_drift_3 linear_drift_4 out.txt graph.txt 0.02 -0.02 0.038 -0.038 1 -1 

These files are
the program       input file 1   input file 2   results           dechirp factors

This batch file will produce a series of output files beginning with the letter D that are the original wav 
files after dechirping with the factors in the list.
The example names starting with 'out', are results with time and interpretation of coefficients, 
including flags on unusual signals.
The next file names, with the example names starting with 'graph', are the numbers in spreadsheet format. 
Naming the first line in your file 'line 1', the values on odd lines are the correlation coefficients and 
the values on the even lines are the corresponding confidence limits. The Graph file is the outData format stripped 
of everything but the numerical values.
If you graph the values on the odd lines and superimpose a graph of the values on the even lines,
then you can see any unusual signals as values from the odd lines that are below the values of the even lines.
This will appear and a jagged steep graph of coefficients appearing below the zero slope line of the confidence
limits.
