IMPUTE2 - problem with MCMC

Question

[Teresa]

Dear, I've run an imputation using the fallowing command

Impute -use_prephased_g -known_haps_g output_phased.haps -h 1000GP_Phase3.hap.gz -l 1000GP_Phase3.legend.gz -m genetic_map.txt -int 1 1000000 -iter 30 -o Part1_impute

I do not understand why the MCMC iteration are not 30, but 1. (see output)

        reference haplotypes: 5008 [Panel 0]
           study individuals: 959 [Panel 2]
           sequence interval: [100000,5000000]
                      buffer: 250 kb
                          Ne: 2000
           input call thresh: 0.900
     burn-in MCMC iterations: 0
       total MCMC iterations: 1 (1 used for inference)    HMM states for imputation: 500 [Panel 0->2]
                active flags: <-use_prephased_g>

Answer 1

Independently from the version used (I've always used V2) do you know why I'm not able to set the MCMC interation?
