To convert .trc binary data to .txt data that is formatted similarly to the output files from a CAEN DT5751 digitiser:
 
# Copy contents of <code>/unix/pbt/aknoetze/ConversionScripts</code> to a new directory.
# Open <code>trc2txt.py</code> in a text editor.
## Change path to directory containing .trc data files by editing variable <code>dirpath</code>
## Change number of decimal points for each column by editing: <code>np.savetxt(..., fmt=‘...’,...)</code>
# Run <code>trc2txt.py</code>
 
Converted .txt files will be in the copied directory <code>NEWASCII</code>. These new files will possess the same file names as the original .txt files.
 
To concatenate the new data files together into one single file, while in the directory <code>NEWASCII</code>,type:
 
<pre>
cat *.txt > OutputFileName.txt
</pre>
 
 
== Working with LeCroy Scope Trace Files in ROOT using the LeCroyData Class ==
 
The LeCroyData class is defined in <code>SimpleLeCroyRoutines.C</code>, which can be found at <code>/unix/pbt/users/dwalker/LeCroy</code>.
The class is intended for use in interactive ROOT sessions, but can be used in compiled ROOT applets. Its public methods and their use are summarised below:
