I am having a similar problem.
I would like to keep the first 13 columns in the text file and get rid of the remaining. The header can stay or not as it is ignored in my analysis.
I tried the code below, but it either didn't work because of the header.
blah = importdata('tdump00120100.txt');
datayouwant = blah.data;
Struct contents reference from a non-struct array object.<--error message
Or I ended up with a long column of data instead of rows.
Any help would be appreciated. I have lots of these files to do.
Thanks bunches.

blah = importdata('1_rowdel.txt');
datayouwant = blah.data;
save('mydata.txt','datayouwant','-ascii')
