Select the content of a cell of an array as variable name in a dataset?

I would like to change the dataset variable name with the content of one cell of another array but I got this error:

Error using dataset/subsasgnDot (line 31) NEWNAMES must be a nonempty string or a cell array of nonempty strings.

The comand used is :

test.Properties.VarNames{1} = raw(1:1);

And the content of raw(1:1) is 'type of device', since raw is a read xls appears the name between ''.

Thanks in advance,

Please post the type of raw(1). I guess this will work:

test.Properties.VarNames{1} = raw{1};  % Curly braces
