If it is a matter of "relationship" (in the sense that a set of proteins
behave i.e. go up or down in the same way over a given treatment), then
any k-means algorithm will do the trick. I'm pretty sure this would be a
no-brainer for you. I'm actually surprised they don't give it a go by
Anything else (like your second point...though I'm curious about the
experimental design) you'd have to give more details, say:
BTW...If you don't want to do it, then don't. Technically, if the person
is doing a PhD, then he/she should know how to do it themselves anyway
and not just hand it off...
P.S. what is your math background? I should have probably asked that
