cell array to dataset: the use of cell2dataset

I am trying to make a dataset that I can grow over time using the following code:
ds = [fileName,IntegralRange]
biopsy = cell2dataset(ds);
where ds will append two cell arrays and row 1 of each column will become the Variable name in the dataset. However this error keeps being thrown out and I have no idea how to fix it:
Error using dataset/subsref (line 396) Not valid dataset object field.
Error in cell2dataset>dfltDatasetVarNames (line 192) names = dummy.Properties.VarNames;
Error in cell2dataset (line 179) d = dataset(cell2struct(vars,dfltDatasetVarNames(nvars),2));
Error in IntegrateNew (line 66) biopsy = cell2dataset(ds);

I can't tell what ds is when it gets passed into cell2dataset. This, for example, works:
>> ds = [{'name1';1;2;3}, {'name2';10;20;30}];
>> cell2dataset(ds)
ans =
name1 name2
1 10
2 20
3 30
Can you provide a simple example that's similar to yours but that fails?
