interrogate output from DAMASK_spectral for "error divergence:" evolution.

results in an ASCII datafile containing the increment counter with corresponding divergence value. the evolution within an increment i is stretched between i and i+1 (and likely jumps then for the next increment i+1 at the value i+1)
