Download it here: Compare sets.
Let’s say you have two or more sets of genes and that you want to calculate the genes common to both sets. Place each set in a text file in which each gene is a line, then run “compare_sets”. The program output is a third file listing the common genes. The program can be easily modified to calculate different comparisons, such as the genes in both sets that are not common, or the genes of one set that are not found in the other. Instructions for modifying it are included in the program’s header.
