Removing the Practice Trials on AAT (mouse version)

I am clueless with coding and wondered if anyone was able to help me edit the AAT (mouse version) http://www.millisecond.com/download/library/AAT/ 
I am getting participants to run the same programme 3 times in total so for the second and third time I was hoping to remove the practice trials. Would anyone be able to help me in this matter. 

Kind Regards

Create at least two AAT scripts:
- One identical to the original (including the practice block),
- One without the practice block

For the latter, simply remove block practice_AAT from the <expt> elements' /blocks attributes:

<expt>
...
/ blocks = [
    1 = SequenceGenerator;
    2 = practice_AAT;
    3 = AAT;
]
...
</expt>

becomes

<expt>
...
/ blocks = [
    1 = SequenceGenerator;
    2 = AAT;
]
...
</expt>


Then administer the two scripts via a simple <batch>:

<batch>
/ file = "aat_mouseinput.iqx"
/ file = "aat_mouseinput_no_practice.iqx"
/ file = "aat_mouseinput_no_practice.iqx"
</batch>
