cw=[1 2 6 1 1 2 2 2 2 4 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5];
fmt=sprintf('%%%dd',cw);
% file open preamble code here for opening file, return valid fid
data=cell2mat(textscan(fid,fmt,'collectoutput',1));
Above presumes all are integer fields, if data does include floating point values fix up format fields to match.
PS: Do not use user ids for tags in future...
