I am using textscan to read a .txt file into matlab but i am having some troubles. The data looks like (first two lines)
1950 "Afghanistan" 8150.368 n/a n/a n/a n/a n/a
1951 "Afghanistan" 8284.473 n/a n/a n/a n/a n/a
and i am using textscan as
PWT = 'Data ind\PWT6.txt';
fid =fopen(PWT);
tmp = textscan(fid,'%f %q %f %f %f %f %f %f','delimiter','\r');
The first column is read ok, the countries are all stored on tmp{1}, but it seems like all the rest is stored in tmp{2} when i actually only want the countries there. Am i using %q wrong or what is going on ?
Thanks :)

"delimiter" is the character used to recognize the end of strings, so when you use \r you are asking the string to go to the end of the line.
What you should do is fopen(PWT, 'rt') for text mode, and not set a delimiter.

You did not add the treatasempty option
tmp = textscan(fid,'%f%q%f%f%f%f%f%f','TreatAsEmpty', 'n/a');
Also remember to fclose(fid) afterwards.
