Auto-generated import data script does not run

Hi,

I'm using the import tool to import some data. The import tool works just fine, but the automated script it generates (attached) throws an error that seems to be related to its syntax:

"Undefined function or variable 'raw'.

Error in Untitled2 (line 38)
rawStringColumns = string(raw(:, [1,2,3,4,5,6,7,8,9,10,11,12,13,14]));"

Can you please check and tell me what may be going on?

Thx!

The file you attaches has a difference from the script file uiimport tool generate for automatically loading data from a general type of file. The file should have few lines before

numericData = NaN(size(dataArray{1},1),size(dataArray,2));

defining the raw variable. Are you sure you haven't accidentally deleted those lines? Try generating the script again.

Thanks Ameer - I did generate the script again, but it came up exactly the same... however, prompted by your comment, I generated a script based on a second dataset, and that created the few extra lines I was missing:

raw = repmat({''},length(dataArray{1}),length(dataArray)-1);
for col=1:length(dataArray)-1
    raw(1:length(dataArray{col}),col) = mat2cell(dataArray{col}, ones(length(dataArray{col}), 1));
end

The difference between the two datasets is that the first had tagged all columns with 'categorical' as data type, while the second set had one column tagged as 'text'. Somehow, the dataset that had all as categorical did not generate the extra lines of code.

Thanks!

That's true, I just tested and found this issue in R2017b that if all columns are categorical, these lines are skipped. This might some bug. R2018a produce a correct script file.
