Thanks very much.

Hi Alfonso,
first of all, you might consider using the variable "NUM", since it already contains the numbers as double variable. So no need to convert anything. You usually use the RAW format, when the format of the EXCEl file changes, i.e., the indexing into NUM get's more complicated. If RAW(2:end, 65) contains only numbers (as numbers, not strings), probably simply doing
FaceRecall = cell2mat(RAW(2:end, 65));
or
FaceRecall = [RAW{2:end, 65}]';
should both work ...

But as I said, maybe
NUM(:, 65)
leads to the same ...

A string is a 1Xn matrix of type char
S = 'hallo';
You can convert it to a numerical matrix using
M = double(S);
If that is not what you want, please give us more details, and a sample string.
