Very large matrices for very large genome
...ion data. This means
about 27,000 genes, each with a vector of numbers reflecting expression at
different tissues and times. I need to do an all against all co-expression
calculation (basically, just calculate Pearson's r for every gene-gene
pair). I try to store the result of such a thing in a 27000x27000 matrix,
but r seems not to like allocating such a large beast. Any
recommendations?
I also rather want to then manipulate the all-against-all interaction
data, treating it as a graph with edge weighted by the r^2, eliminating
some edges, maybe even finding network motifs like cliques, etc., so
