Hi all,

Basically I want to make a binary hit matrix.

For instance, if I have a file called 'pair.txt':

set_a    gene_1
set_a    gene_2
set_a    gene_3
set_b    gene_3
set_b    gene_4
set_b    gene_5
set_c    gene_1
set_c    gene_3

And I want to convert it to a binary matrix as:

Rows    set_a    set_b    set_c
gene_1    1    0    1
gene_2    1    0    0
gene_3    1    1    1
gene_4    0    1    0
gene_5    0    1    0

Can anyone suggest how to do this?

Thank you!

Alex
