Why does textscan only read the first row of my text file?

7 views (last 30 days)
for file = 1:total_files
[inputfile,path] = uigetfile('*.txt');
fileids{file} = fopen(fullfile(path, inputfile));
if fileids{file} == -1
error('Failed to open file "%s"', fullfile(path, inputfile));
b = textscan(fileids{file},'%n %n %*n %*n %*n %*n %*n',-1, 'delimiter', '/t');
events = b{1};
event_times = b{2};
I want to read in only fhe first two columns out of 7. This works. However, I can only read in the first row.

Instead of using the below line,
b = textscan(fileids{file},'%n %n %*n %*n %*n %*n %*n',-1, 'delimiter', '/t');
use this,
b = textscan(fileids{file},'%n %n %*[^\n]', -1, 'delimiter', '\t', 'EndOfLine','\r\n');
you will be able to access the data properly.
Hope this helps!

Thanks! What if I now want to access the other columns, from 3 to 7? Why doesn't it become:
b = textscan(fileids{file},'%*[^\n] %n %n', -1, 'delimiter', '\t', 'EndOfLine','\r\n');
I'm trying it out but I get this error:
Index exceeds the number of array elements (5).
Error in SocialTest (line 21)
count = b{6};
