Reading a text file without headers

Hi,

I have a text file without headers and starting as shown below with spacing. I have 3652500 rows in the text file. How can I read this text file using MATLAB.

 1    1    1    1   0.00    55.    36.   295.

Thanks in advance,

If all rows have the same number of columns

dlmread, Read ASCII-delimited file of numeric data into matrix

Syntax

    M = dlmread(filename)
    M = dlmread(filename, delimiter)
    M = dlmread(filename, delimiter, R,C)
    M = dlmread(filename, delimiter, range)
.

Example in response to comment:

This works fine here (R2013a)

    filespec = 'h:\m\cssm\sample\sample.txt';
    num = dlmread( filespec );
    whos num

returns

    Name       Size            Bytes  Class     Attributes
    num       20x8              1280  double

Doc says

    When dlmread infers the delimiter from the formatting of the file, it
    treats repeated white spaces as a single delimiter. By contrast, if you
    specify a delimiter, dlmread treats any repeated delimiter character as
    a separate delimiter.

Hi,

Thanks. I got this error.

Error using dlmread (line 141) Mismatch between file and format string. Trouble reading number from file (row 1u, field 1u) ==> @BCDE

I have attached a sample of the file (sample.zip). Can you please have a look at it if possible?

Thanks.

You've marked it as "Accepted" , so is it still not working or did you figure it out?

[Damith]

no it is not working yet. See the error in my above post.

I tried this code

M = dlmread('OUTPUT.txt', '\t');

I am getting this error

Error using dlmread (line 141) Mismatch between file and format string. Trouble reading number from file (row 1u, field 1u) ==> @BCDE

Anybody have an idea.?

See the example, which I added to the answer.

sample.zip, which you attached, contains a file named sample.txt. This file is not tab delimited, but space delimited.

I failed to reproduce your error.
