Error with T_predic function rom the tool box t-tide

Hello all,

I tried to use the function t_predic from the toolbox t-tide. However, i do not understand how to fill the part in bold and underline. I knoe it's the tidal constituants but i dont know how to input them properly to make the t-predic function working properly. I did not find any example on internet...

From the function explanation: YOUT=T_PREDIC(TIM,NAMES,FREQ,TIDECON,LATITUDE,SYNTHESIS);

What i did: y=t_predic(time,TG1,0.5,'latitude',53.236993,'synthesis',0);

Can someone help me, please?
