check the empty cell of a table.

Hi guys, I am trying to read table from txt file and split it to two parts. So, I am reading as myTable.Column(X:Y). Y depends on the total lines of the txt file. But I cannot check the empty cell on it for stopping the loop and I got error 'index exceeds array bounds' I tried isempty() but it didn't work can you help ? stim_duration=2;

 array4A_1=[];

           write2 = fopen('PARTA.txt','wt');
         while (t_count<line/(stim_duration*128*2))
            part=1*foo;  
            temp=128*sec_2;   
             while(part<temp)
                ss_A=ss_A+ sum(table.FIRST(part+1));%%%burayı bir eksilt 
                B4A_1=[array4A_1 ;table.FIRST(part+1)];
                fprintf(write2,'%s\n',table.FIRST(part+1));
                array4A_1=B4A_1;           
                    part=part+1;

             end
           foo=128*2*sec_3; %%          
            sec_3=sec_3+stim_duration;           
            sec_2=sec_2+(stim_duration*2); 
            t_count=t_count+1;        
         end          
         save('1_COL_A','B4A_1');
         AR=std(B4A_1);
         disp('1.COLUMN A PART DEVIATION:');  
          disp(AR);
         mean_A4_1=ss_A/(128*stim_duration*t_count); 
         write = fopen('PARTB.txt','wt');
        %%1. COLUMN PART B
        array4B_1=[];
        et=0;
        while(et<13)      
           partb=1*q*128;     
            temp2=128*u*2;  

              while(partb<temp2)                     
                ss_B=ss_B+ sum(table.FIRST(partb+1));            
                B4B_1=[array4B_1 ;table.FIRST(partb+1)];
                fprintf(write,'%s\n',table.FIRST(partb+1));
                array4B_1=B4B_1; 

                partb=partb+1;
              end
            q=q+4;        
            u=u+stim_duration;
            et=et+1;               
        end
         save('1_COL_B','B4B_1');
         AR2=std(B4B_1);
         disp('1.COLUMN B PART DEVIATION:');  
         disp(AR2);
         disp('MEANB');
        mean_B4_1=ss_B/(128*stim_duration*et);
        disp(mean_B4_1);

i split the parts as every 128*2 times.

Rather than reverse-engineering your code, could you make it easier for us to know which loop is causing you the problem? I counted 4 while loops.

Also, to increase readability (and the probability of someone helping), you could format your code better. In the matlab editor, highlight all of your code, then press ctrl+i. This will properly indent your code.
