Hi @Brendan,

What is the error you are recieving exactly?

[Brendan]

Not enough input arguments.

Error in isfread (line 22)

fileID = fopen(filename,'r');

When using isfread by jhon lipp

So in the code available for isfread here:

isfread - File Exchange - MATLAB Central (mathworks.com) [Go to functions tab and click on isfread]

The line is different from the one you've shown

fileID = fopen( fullfile(folder, fileName), 'r');

Maybe thats causing the error. Could you compare the isfread function on your system to the one given in the site and see if they are the same?

When I use that code i get the error : Error using isfread

No file name, directory or pattern was specified.

[Divyajyoti Nayak]

If you look into the code, the first if statement has this error message. It checks the existense of the argument pattern.

Since, this error message is popping up it means you haven't called the isfread function with the correct argument.

isfread(Filename) %Make sure the file is in the same directory as your script

If this is not the case then can you please share the code you are working with along with any isf file?

See this post on the Tektronix site. It tells how to save the file as a .csv file. After that, use readtable or readmatrix to import it.

That step might not be absolutely necessary, however without the file itself, I can’t determine that. To upload the file here, use the zip function, then upload the zipped file (providing that it’s within the file size limit).
