a=('D:\TEST');      
b=dir(fullfile(a));         
L1=length(b);   
k=1;
for i=3:L1                
      c=dir(fullfile(a,b(i).name));        
      L2=length(c);
      for j=3:L2-3
          d=fullfile(a,b(i).name,c(j).name);  
          g1(k,:)={c(j).name}; 
          e=load(d);           
          n = e/2.5114;      
          x1=detrend(n);
          y=fft(x1);
          pow=y.*conj(y);
          l=length(y)/2;
          freq=(-l:l-1)*250/length(y);
          total_pow=sum(pow);
          pk=findpeaks(pow);
          k=max(pk);
          k1=k-0.001;
          [p2,k2]=findpeaks(pow,'MinPeakHeight',k1);
  %  Amax=max(p2);  
   k3=max(k2); 
   fmax=freq(k3);
   if ((fmax>24.5)&(total_pow>40))
       d1={'Event'};
   else
       d1={'Not Event'};
   end
         t(k,:)=[total_pow d1];
         k=k+1;
      end
  end

i am getting following error.....

>>new_seismic_first
Subscript indices must either be real positive integers or logicals.
Error in new_seismic_first (line 39)
       t(k,:)=[total_pow d1];

k is not an integer or valid index for your array t.

I did not inspect your code in details but you can simply add a different counter such as u = 1; before your for loops and change it as t( u, :) and u = u+1; it should be enough.
