PREPARATION

There are two ways to access your data for analysis.
After scans save files before conducting analysis.
Name files in an organized format to make it easier to identify and locate for future use. 082909scansun is an example.
08 stands for August, 29 stands for the day, and 09 for the year. Scansun identifies the source. The naming system needs to be consistent.
All files are saved to the PARI main server and stored under username and type of file.
