number of rows text file

I have opened a txt file using the following code , and i see that there are 1000 lines which i can access,but length or size commands dont show the number of lines extracted(as shown in the attached photo),how can i get the number of lines.

Thanks

fid=fopen('test2.txt');
g = textscan(fid,'%s','delimiter','\n');
fclose(fid)
g{1}{4:71:10000}

Try

length(g{1})

Your g will be a cell...you can access your required line n using g{1}(n)
