Matlab function to read data files having .Cmn extension

17 views (last 30 days)
I want to open and read data files in Matlab having extension '.Cmn'. Please inform me weather there is any Matlab function to open and read this type of data files. I could not attach a sample data file here as the file format is not supported.
I don't know much about CMN files. Some information is provided in the website 'FilExt' as "the CMN file type is primarily associated with Systems Management Server (SMS) by Microsoft Corporation.You need a suitable software like Systems Management Server (SMS) from Microsoft Corporation to open a CMN file."
The website recognizes the file as a 'text file' but I couldnot read the file in Matlab using the 'textscan' function. Also the 'online viewer' in the website reads the data file as:

Thanks for the suggestion. I have now attached a zipped sample CMN data file.
I wish to read directly the CMN data file. And I don't need the first two lines.

Try the following code. It ignores the first two lines of the file and starts from the line
MJdatet ...
The first row is used as column names for the table, and the rest is used as numeric data.
f = fopen('data.txt');
data = textscan(f, '%s%s%s%s%s%s%s%s%s%s', 'HeaderLines', 2);
data = [data{:}];
fclose(f);
column_names = data(1, :);
numeric_data = data(2:end,:);
numeric_data = cellfun(@(x) str2double(x), numeric_data);
T = array2table(numeric_data, 'VariableNames', column_names);

Yes, that would heve been a better solution.
Following will also work
readmatrix('data.txt', 'NumHeaderLines', 3)

I can now directly read CMN data files using the below code:
% Read CMN data files
f = fopen('chum350-2015-12-16.Cmn');
file_data=textscan(f, '%f %f %f %f %f %f %f %f %f %f','headerlines',3,'delimiter',' '); % reading the text file and extracting the data in a cell
Raw_data=cell2mat(file_data); % converting cell data into a mat file
