multiple paired t-tests

I'm not really looking for a needle in a haystack, there are a small
number of the 60 tests (about 20) that are likely to concord with other
experiments I have, and in a particular pattern. Since I already have
the data in tables for graphic depiction, I was hoping to have a
reasonably easy way to find whether this way the case. It seems so.

So it's not a matter of finding a needle in a haystack, but more finding
a patch of embroidery that I know the pattern of. It still might be a
woven bit of hay, but it's not as likely.

so you want to find a needle in a haystack, not an easy task. You should 
account for multiple tests, which is as far as I can see not done in the 
code yet - or you have to accept that you find a bunch of hay which 
accidentally looks pretty much like a needle.
There are some solutions in doing such things for instance finding 
relevant SNPs in microarray data. Maybe your task is quite similar.
