Fixed counting the right brackets for sorting.

python_ast/sort_dataset.sh

 #!/bin/bash
 
 #      | sort by number of nodes (equivalent to number of "{"), remove duplicates
-cat $1 | perl -F{ -lane 'print "$#F $_"' | sort -n | cut -d' ' -f2- > "${1%.bracket}_sorted.bracket"
+# cat $1 | perl -F{ -lane 'print "$#F $_"' | sort -n | cut -d' ' -f2- > "${1%.bracket}_sorted.bracket"
+cat $1 | awk '{print gsub("{","{")-gsub("\\\\{","\\{"), $0}' | sort -n  | cut -d' ' -f2- > "${1%.bracket}_sorted.bracket"
