Cycle number with minimum Rwp?

Is there are way to output to file the cycle number that had the minimum Rwp?

continue_after_convergence
randomize_on_errors
num_iters 100000
num_cycles 100
'otherstuff

Not that I know of, short of a tedious external python script.

The following works:

prm best_rwp 1e10 val_on_continue = If(Get(r_wp) < Val, Get(r_wp), Val);
prm best_cycle 0 val_on_continue = If(Get(r_wp) == best_rwp, Cycle, Val);

best_cycle is updated and can be outputted to a file.

However, it may well be best to see all of the data using out_prm_vals_on_convergence.
