You are welcome, Atunu. I can not guess the problem unless I see the file.

Thank you, Iftekhar.
I tried to do this as well. But the error message is now:
DataA = dlmread("test1. asc", ',');
"Mismatch between file and format string.
Trouble reading number from file (row 2, field 1) ==> ;...\n"
Thank you for the help.

It seems like the format of the file is not correct for dlmread. I guess it may
have text column headings (possibly DataA). The function dlmread expects only
numbers separated by delimiters. You can try after removing those column headers
(if any). If still not woking, you may consider sending us a sample file.
Thanks

Thank you for the response and suggestions.
I actually tried dlmread, textscan, textread, fread and more that are
suggested in the matlab help info and online tutorials. Nothing letting me
continue working on this ascii data file which has about (22000, 2) data as time
and frequency but the different files have different data sizes. I had
different type of errors at different attempts while trying to read this
datafile but the recent one is just noted below :
Error using ==> dlmread at 145
Mismatch between file and format string.
Trouble reading number from file (row 1, field 1) ==> DataA
I can use importdata but how can I manage to use the data as time and frequency
dimenstion ? I am sorry if the question is too naive. But I need to apply
filtering on this datafile. Usually I see one dimensional audio file but this
type of data file I have not found yet as an example on the web.
Thanks for any further suggestions

Hi Atunu,
If I understood your question correctly, you can use the function
'dlmread'. Try the command:
A=dlmread(filename, ',');
Thanks

Hello Matlab_DSP Experts,
How can I read the following file snap shot in matlab: the first column is time
and the second column is frequency:(the file has originally more than 22000
sample points, I omitted this here for brevity)
Data A = [
0.34234, -.032312132; ...
0.35667, 0.23456723;. ..
0.36789, 0.98674346;. ..
1.09875, -0.99875654; ...
1.34343, 1.34234343];
Thank you for any suggestions.
P.S. I am not sure sure if the email message is gone thorough. For repeated
message, my apology.
