fprintf to create a file / precisions

Hey Guys, this code is supposed to write Data into Test.dat-file.However, it doesn't work, cause signal is an Cell-Array containing strings.So can u pls help me and correct the code.

fprintf(fid,'%i\t%i\t%i\t%f\t%i\t%f\t%s\n',index,addr,amptotal0,amptotal,amp2,theta,signal)

And if u have some minuts.....the precisions... %f means float / %i menas integer but what does the t and the n mean ?
