textread not working with .text file

Before I try to apply textread to the .txt file, I have already split up the file from a large text file to smaller text files using a script which is successful in its execution and uses functions fopen, fgetl.

 Large Text File -> Small Text File 1, Small Text File 2, Small Text File 3

Output of Small Text File 1:

 Run Lat Long Time

 2 1 13 3

 2 3 3 3

 3 3 5 12

From the split up text file -- small text file 1 -- which is in column format, I apply textread and returns a mixture of random (scattered) data from the text file (random sample of data from col2 and col3).

In the code: the function is the basic:

 [col1 col2] = textread('smallfile.txt', '%d %d');

 Output Return: 3 12 13 5

 Not what is in Col1 = 2 2 3

I have tried to fix it by checking ANSI encoding and applying rt in my opening function. But no success.

Thanks,

Amanda

Is there a particular reason you are using textread? The importdata function might make your life easier. Also, some example data would help in understanding the problem.

Are you using textread() or textscan() ?

I have update the question to be clearer. I'm trying to get the data in columns for plotting.

textread() is going to read all the data on the line, not only as many columns as you provide %d for.

Answer 1

You could use:

[A,' ', 1] = importdata('myFile.txt);
%And the variables you want:
col1 = A.data(:,1);
col2 = A.data(:,2);

For more info

help importdata

And if you need low level routine:

help fscanf

Definitely works with the integer data. Not working well with string data. I know that I didn't put this in my example but I have one significant column of string data which I would like to pull in as a column. I happy with the integer column data. Thanks.

Look inside A.textdata, all text data should be in there. More details in:

help importdata

Cheers!

Perfect Columns. Excellent!
