If you have read your file to a table, you can just remove the variable. If you read your file as a char matrix, you can just remove the first 9 element (with A(:,1:9='';) and remove the top row (with A(1,:)='';).

Dear Roy, I don't know how to read the file like a table or matrix...

Did you find a solution? If not, the code below should help:

fid=fopen(filename,'rt');
data=textscan(fid,'%s','Delimiter','\n');
fclose(fid);
