why am I getting this error ? Any help please

9 views (last 30 days)
for i = 1:length(file_list)
filename = file_list(i);
data_in = readtable([path_n filename]);
Error using readtable
"filename" must be a string scalar or
character vector.
Error in READ_MULTI_FILES (line 10)
data_in = readtable([path_n filename]);

files = dir('*.Cmn');
for i = 1:length(files)
data1 = files(i).name;
f = fopen(data1);
data = textscan(f,'%f%f%f%f%f%f%f%f%f%f', 'headerlines',5,'Delimiter','');
fclose(f);
% GET DATE
MJ{i} = data{1};
MJ = {cat(1,MJ{:})};
MJ_date = MJ{1,1};
end

[file_list, path_n] = uigetfile('*.Cmn','Grab the files you want yo process','Multiselect', 'on');
if isnumeric(file_list)
return; %user cancel
end
file_list = cellstr(file_list);
for i = 1:length(file_list)
filename = file_list{i};
data_in = readtable(fullfile(path_n, filename));
subject_id(1,i) = string(filename(1:end-4));
VTEC = data(:,9);
STEC = data(:,8);
time = hours(:,2);
[H,M,S] = hms(time);
scatter(H,VTEC, 'k', H,STEC,'o');
hold on
end
leg = reshape(subject_id + ["_V"; "_S"], 1, []);

Thank you so much for the help.
i modified the previous suggestion (you gave in the link above) and this modification works perfectly for me
files = dir('*.Cmn');
for i = 1:length(files)
data1 = files(i).name;
f = fopen(data1);
data = textscan(f,'%f%f%f%f%f%f%f%f%f%f', 'headerlines',5,'Delimiter','');
fclose(f);
% GET DATE
MJ{i} = data{1};
MJ = {cat(1,MJ{:})};
MJ_date = MJ{1,1};
end
