I am trying to convert the string into binary and sequencing with DNA,but i am getting error as follows :

Attempted to access bases(145); index out of bounds because numel(bases)=4.
Error in ==> filename at 21
result((k+1)/2) = bases(index);

What is the solution for this? Here is the code:

clc;
ui=input('enter the message:','s')
decString = unicode2native(ui,'utf-8')
hexString = dec2hex(decString)
binaryArray= dec2bin(decString,8)
bases = 'ATGC';
for k = 1 : 2 : length(binaryArray)
    % Convert these two digits into a number 1 - 4.
    index = 2 * binaryArray(k) + binaryArray(k+1) + 1;
    % Use that index to assign a letter to our result.
    result((k+1)/2) = bases(index);
end
% Display in command window:
result

Thank you

It is giving error like index exceeds (4)

Yes, that is exactly the problem that was discussed in the Answer.

bases has only 4 elements so index must stay in the range 1,2,3,4 not 145 like you have it. Think about the logic some more.

The solution i got was

TGAC
TCAG
TCGT
TCAA
TCTA
TGCC

Its a vector right?

i want it to be something like this

TGAC
TCAG
TCGT
TCAA
TCTA
TGCC

i have to this sequence to other side.

I do not see the difference between what you got and what you want.

To answer your question, though: No, it is not a vector, it is an array. Character strings in MATLAB are arrays, not individual entities. The "result" variable above is char of size 6 x 4

If you want it as a cell array of strings, then use cellstr(result)
