Hummm! When I typed maM(ka.susc.norm) I see a matrix with 4 colunms x 7680
rows. (Please, see it below).

But, my genes are duplicated in the nylon filter membrane!

Then, I should have only the half (3840 genes).

Which will my error be?

Thanks

[7680,]         NA            NA           NA

The last two rows is Zero(0), because it is blank (spoted water without
DNA). I have 530 blanks in my array.
