This directory contains the perl code used to find all
knots obtained from projections of each of the 1288 prime 
alternating 12-crossing knots, by changing every subset 
of the crossings and using Knotscape's "knotfind" program 
to identify them. The Perl file "rerun12run170507.pl", run
from inside the "bin" directory of Knotscape (so that
it can call "knotfind") will recreate the "rerun12output0.txt"
file, containing the data. The file "12s_for_snappy.pl", which
runs on the "12_12.txt" file in the sliced directory, which
contains the 10768 12-crossing projections that resulted,
extracts all of the DT codes, and the python file 
"run12s_snappyb.txt" when run in SnapPy will identify all of
these 12-crossing knots. 

"rerun12run170507.pl" ran with no errors.

The results of running "run12s_snappyb.txt" can be found in 
the file "12cr_identrerun.txt".
