    261261The next and final step is to copy the geo_em and the namelist.wps files to a directory with the name chosen for the domain (e.g. Europe_15k). This folder must be located in the path specified by the variable `WRF4G_DOMAINPATH` in [wiki:WRF4Gresources_wrf4g resources.wrf4g]. After following these steps, the new domain is available for using it in any WRF4G experiment, just setting the variable domain equal to the name of the directory in [wiki:WRF4Gexperiment_wrf4g experiments.wrf4g] (the folder where we located geo_em_d01.nc and namelist.wps).

     264== How to reconfigure the features of one experiment ==
     265If you want to reconfigure the features of an experiment and you execute `wrf4g_prepare`, you will probably see:
     266{{{
     267#!sh
     268[user@mycomputer~]$ wrf4g_prepare
     269Warning: You are using resources.wrf4g located in the /home/carlos/WRF4G/etc/ directory.
     270Experiment already exists
     271}}}
     272In order to do it, you need to execute `wrf4g_prepare --reconfigure`. In the example below, we are going to expend the `end_date` of one experiment.
     273{{{
     274#!sh
     275[user@mycomputer~]$ cat experiment.wrf4g | grep "end_date="\"
     276end_date="2011-08-30_00:00:00"
     277
     278[user@mycomputer~]$ cat experiment.wrf4g | grep "end_date="\"
     279end_date="2011-09-01_00:00:00"

     301== How to resubmit an experiment ==
     302If one experiment has finished with an error and you want to rerun the experiment again. You have to execute:
     303{{{
     304#!sh
     305[user@mycomputer~]$ wrf4g_submit --rerun -f -e test1
     306Submitting realization: "test1"

     309        Submitting Chunk 3:     2011-08-29_12:00:00     2011-08-30_00:00:00

     311
     312== How to rerun a specific chunk of a realization ==
     313
     314Imagine, you want to resubmit the chunk number '''1''' of the realization '''test2'''. In this case, it is highly recommended that you use the option `--dry-run` of `wrf4g_submit` command before you submit your chunk in order to make sure you are submitting that chunk an nothing else.
     315{{{
     316#!sh
     317[user@mycomputer~]$ wrf4g_submit --dry-run --rerun -c 1 -f -r test2
     318Submitting realization: "test2"
     319        Submitting Chunk 1:     2011-08-28_12:00:00     2011-08-29_00:00:00
     320
     321[user@mycomputer~]$ wrf4g_submit --rerun -c 1 -f -r test2
     322Submitting realization: "test2"
     323        Submitting Chunk 1:     2011-08-28_12:00:00     2011-08-29_00:00:00

    264329In this example, we are going to simulate an experiment with independent realizations which has [wiki:WRF4Gexperiment_wrf4g#Experimenttime-specification| multiple_parameters flag] activated. The experiment is composed of five realizations with three chunk per realization. In order to use [wiki:WRF4GCommandLineInterface#wrf4g_kill  wrf4g_kill command], we are going to first submit the `wrfuc_physics` experiment.
