Help with textscan classifier

Hello,

Trying to extract data from a text file, the data is in the format:

Eu3+ 1 10.06037350 -4.673610300 -1.834337367

Currently I am trying C = textscan(fid,'%s%d8%f32%f32%f32');

However this returns: C = {1x1 cell} [1] [10.0604] [-4.6736] [-1.8343]

So can anyone tell me what classifier I would need for the Eu3+ entry?

Many thanks,

Tom

Hi!

What's wrong with the result? What is "Eu3+"? Is it a string?

[Tom]

Eu3+ 'physically' refers to an atom type (europium), and the numbers which follow are x y z coordinates. The text file contains an enormous list of a few different atom types and their coordinates, so I presumed the output would return 'Eu3+' and not just [1x1 cell] so I could later refer to the following coordinates as corresponding to that atom type.

... sorry if that doesn't answer your question. I'm struggling after a long period from Matlab.

Your current output does seem to be what you want.

str = 'Eu3+ 1 10.06037350 -4.673610300 -1.834337367';

C = textscan(str,'%s%d8%f32%f32%f32')

C = 

      {1x1 cell}    [1]    [10.0604]    [-4.6736]    [-1.8343]

Look at the contents of the first cell:

C{1}

ans = 

      'Eu3+'

Hi!

You can write

C{1} = char(C{1});

This way you get a character array with each line corresponding to an atom type.

Or you can create a new cell array from C

Cnew = cell(length(C{1}), 5);
% loop over all rows
for r = 1:length(C{1})
  % loop over all columns
  for c = 1:5
    if c == 1
      % atom type as string
      Cnew {r, c} = char(C{c}(r));
    else
      Cnew {r, c} = C{c}(r);
    end
  end
end
