It is greatly recommended that if you need to delete something from a text file, that you copy the parts that you want to keep to a new file, possibly renaming files afterwards. Deleting text from an existing file is messy.

I don't want 4:
I used
c = textscan(f,'%f %f %s','headerLines',1);
I got:
c =
[1666394] [] {}
how I can textscan to return c{1} as:
1666394
1759415
1959936
998862
2625420
thanks
