E2 - abnormal permutation pairs hard version
WebThen, shortest path genes with permutation FDRs less than 0.05 were selected as candidate genes. Obtained candidate genes for each pair of tissues are provided in Table S2, and numbers of these candidate genes is listed in column 3 of Table 3. Several shortest path genes were screened out, and the number of possible genes sharply decreased. WebJan 5, 2013 · Viewed 7k times. 9. I need to generate all possible pairings, but with the constraint that a particular pairing only occurs once in the results. So for example: import itertools for perm in itertools.permutations (range (9)): print zip (perm [::2], perm [1::2]) generates all possible two-paired permutations; here's a small subset of the output:
