Example of creating tuple from text file (Appendix)

We start from file that constains events each presented in two lines

awk '{print $2,$5,$6,$7}' extractedDataPred2.txt > epip_hb.txt

this command takes two lines from the input and joins them into one line

paste - - < epip_hb.txt > epip_hb_joined.txt
