Dear Hajar Bagherian,

Once you have created several files from jobs in parallel, the easiest way
to process them is to use FLAIR:

Go to the "Run" -> "Data" menu, click on one of the scorers in the
Usrxxx-Window and "Add" all the corresponding files (ending in "_fort.xx"
where "xx" is the logical output unit number of the scorer). Then clicking
"Process" will create a combined output file from the original files
(including the statistical uncertainty). Note that this only works if your
*_fort.xx-files are unformatted (binary output).
