change repetition number in ANT-short

Hi,

I am trying to change the repetition number for the short attentional network task. The default number in the task is 5 repetitions for each condition and I want to reduce that to 3 repetitions. Is there any way that I can change that? Seems like the number of trials is set in the experimental block. 

Thanks

Simply reduce the amount of trials in the block from 120 to 72:

<block ANT>
/ onblockbegin = [values.blockcount += 1]
/ onblockbegin = [values.practice = 0]
/ trials = [
    1 = getReady;
    2-121 = noreplace(nocue, centercue, spatialcue);
]
</block>

 becomes

<block ANT>
/ onblockbegin = [values.blockcount += 1]
/ onblockbegin = [values.practice = 0]
/ trials = [
    1 = getReady;
    2-73 = noreplace(nocue, centercue, spatialcue);
]
</block>
