Please forgive me for jumping into the discussion: what is the syntax precisely? Is this feature implemented in all the applications? I've tried using MEASURE_CORRELATIONS[SzSz,INITIAL_SITE=0]="Sz:Sz" with dmrg, and it gave me same N*(N-1)/2 values. Best, Zhenya

Thanks for the quick response. This is exactly what I thought(and did). However to my surprise, the output file of " ladder " is so large (compared to the usual square lattices), it is impossible to " firefox " or " convert2tex " the " *.tast1.out.xml " file! Any suggestion will be appreciated!
Since your lattice does not have translational symmetry any more, all the combinations of two sites (N*(N-1)/2) will be measured and stored independently. If you are interested in the correlation function from a specific site (say the boundary site), you can specify parameter INITIAL_SITE to its index (e.g INITIAL_SITE = 0), which greatly reduces the output size from O(N^2) to O(N).
