How to remove this error?

My code is giving following error. How can I fix it?

Index in position 1 exceeds array bounds (must not exceed 2048).

Error in Create_Obs_data (line 64)

synth = synth(1+t0_i:nt+t0_i,:);

The error message is telling you that synth only has 2048 rows, but nt+t0_i is greater than 2048, i.e., you are trying to index a position in synth that isn't there.

Before that line, put this:

whos synth % Don't put a simicolon!

What do you see in the command window?
