I am trying to get this to play two blocks. the first block would have ten sentences at one SNR. the second block would have 60 sentences (30*2 SNRs) at two SNRs. However, I am getting the following error and do not know how to solve it. Any help is appreciated

Index exceeds the number of array elements (1).

Error in SINtest (line 112)

expData.SNROrder(:,1) = SNR_PRAC(randomCond(numSNRs,numREPS));

SNR = [3 8]; %the two SNR conditions

SNR_PRAC= 8; %the only SNR condition I want played in the practice block

NUM_SENT_COND = 30; %the number of sentences per SNR condition for the second block

NUM_SENT_BLOCK_PRAC = 10; %the number of sentences for the first practice block

numSNRs = length(SNR);

numSNRs_PRAC=length(SNR_PRAC);

numREPS = NUM_SENT_COND;

numREPS_PRAC =NUM_SENT_BLOCK_PRAC;

expData.SNROrder(:,1) = SNR_PRAC(randomCond(numSNRs,numREPS)); %HERE IS THE ERROR.
