These scripts are the bulk of a pipeline which calculates VENN diagram numbers.  Here is an example of how to execute the pipeline:

./ *.faa --verbose > hit_table.txt
grep -v -E "epidermi|haemolyticus" hit_table.txt > aureus_saprophyticus_hit_table.txt
grep -v -E "epidermi|saprophyticus" hit_table.txt > aureus_haemolyticus_hit_table.txt
grep -v -E "epidermi|saprophyticus|haemolyticus" hit_table.txt > aureus_hit_table.txt
grep -v -E "aureus|saprophyticus|haemolyticus" hit_table.txt > epidermidis_hit_table.txt
grep -v -E "saprophyticus|haemolyticus" hit_table.txt > aureus_epidermidis_hit_table.txt
grep -v -E "aureus|haemolyticus" hit_table.txt > epidermidis_saprophyticus_hit_table.txt
grep -v -E "aureus|saprophyticus" hit_table.txt > epidermidis_haemolyticus_hit_table.txt
grep -v -E "aureus|epidermidis" hit_table.txt > haemolyticus_saprophyticus_hit_table.txt
grep -v -E "aureus" hit_table.txt > epidermidis_saprophyticus_haemolyticus_hit_table.txt
grep -v -E "epidermidis" hit_table.txt > aureus_saprophyticus_haemolyticus_hit_table.txt
grep -v -E "saprophyticus" hit_table.txt > aureus_epidermidis_haemolyticus_hit_table.txt
grep -v -E "haemolyticus" hit_table.txt > aureus_epidermidis_saprophyticus_hit_table.txt
grep -v -E "aureus|epidermidis|haemolyticus" hit_table.txt > saprophyticus_hit_table.txt
grep -v -E "aureus|epidermidis|saprophyticus" hit_table.txt > haemolyticus_hit_table.txt
./ *hit_table.txt -p 35 -l .75 -e .00001 -o .lax-common --verbose
./ *.lax-common -o .withdeflines
grep -c Group *.withdeflines

Note, the above example is a little dated, but it shows you how it works.  The script was created to replace the need for the repeated greps.  These commands will take a long time and you need to have blastall and formatdb installed on your machine and in your path.  The final numbers output by the last grep command are the seed numbers to use in the ven diagram, but will replace that last grep command and calculate all the Venn numbers.
Something went wrong with that request. Please try again.
