I'm importing data using the loop below. I'm getting an error that some of the table variables cannot be concatenated because they're a cell in one table and a noncell in another. How an I correct this? The reason for this issue is because in some data files the variable has actual values and for some parts of the files, the data appears as an NaN. Any help would be appreciated
FileID = dir('*.dat');
T = table;
for j=1:length(FileID)
opts = detectImportOptions(FileID(j).name);
Ts = readtable(FileID(j).name,opts,'ReadVariableNames',false);
Ts.Properties.VariableNames=VarNames;
T = [T;Ts];
end

Do the detection once against a file that has numeric in that column and use those options for all of the files.
Alternatively after the option detection bash the setting for that column to make the variable numeric with the appropriate nan detection .

Actually I figured it out! I used setvartype in case anyone wants to know. Thanks for the answer
