I am having trouble with errors in the array used for anova analysis

Sorry for the messy code, but I've programmed a 10x3x3 anova analysis and I'm getting an error code and I don't know what's causing it.

Error Code : The grouping variable must be a categorical vector, numeric vector, logical vector, datetime vector, duration vector, character array, string array, or cell vector of character vectors.

The grouping variable must be a categorical vector, numeric vector, logical vector, datetime vector, duration vector, character array, string array, or character vector cell vector.

Does anyone know the cause?

dataFileName1 = 'AllParmeter_Exp1';



dataFileID1 = fopen([dataFileName1,'.txt'],'r');
if (dataFileID1 == -1);
	error('data file not exist');
end
formatSpec = '%f';

y = fscanf(dataFileID1,formatSpec)


fclose(dataFileID1);

g1 = {1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10};

You forgot to attach ''AllParmeter_Exp1.txt';

If you have any more questions, then attach your data with the paperclip icon after you read this:

Looks like g1 should be a numerical vector, not a cell array (i.e., square brackets instead of curly brackets). e.g.,

g1 = [1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10 et cetera];

Thank you!

The program worked.
