1) What type of error? First error I got was related to absence of number of
repeating. Despite the manual to textread it seems that this input argument
is not optional, so textread(file,format,[],options), or similar, must be
specified.
2) Textread doesn't return single argument. Equal number of outputs to
format specifier must be given instead.
3) It doesn't work anyway. I tried also textscan with similar result, i.e. I
got the output but the parsing was incorrect. Even adding 0\t to several
first lines to got the same formating for those lines didn't help.
4) This code worked just fine:

str = fileread ('test.log');
[s, e, te, m, t, nm] = regexp (str','(\n(\S*)\t(\S*)\t(\S*)\t(\S*)\t)');
nl = size(t,2);
for ii=1:nl
        a(ii,1) = str2num(t{ii}{2});
        b{ii,1} = t{ii}{3};
        c{ii,1} = t{ii}{4};
        d(ii,1) = str2num(t{ii}{5});
end

Maybe the transformation of cell t to desired outputs could be done more
effectively.
