Please do not let the readers ask an internet search engine for finding out, which tool you are using. Edit your question and insert a link to the download page of the "biosig toolbox".

Then post the code you use. The vague description "when i used the sloud" is not useful. Provide a copy of the complete error message also. Why do you assume that "sload" is existing? How did you "install" the toolbox?

Thanks for posting more details.

Prefer to post code and error messages as text, not as screenshots. This is far more convenient for the readers.

I assume your "sloud" is a typo in the forum only. Please fix or clarify this. You mentioned the "gnd" format, but the error message looks like you use a "gdf" file extension. This is confusing.

The solution is pretty simple. The reason you are getting this error is that you might haven't installed the Biosig toolbox properly. Just adding it to the MATLAB path will not make Biosig work (as in case with EEGLAB). To install Biosig properly, go to the Biosig folder in MATLAB and open "biosig_installer.m" in MATLAB. Now run it. If it runs successfully then congratulations! you have installed Biosig toolbox properly. Now run your command:

[s, h] = sload('A01T.gdf');

This should work. Good luck!

Thanks a lot. I have solved this problem. Just download the toolbox in http://biosig.sourceforge.net/ and it runs well.

Hi! I had run successfully de "biosig_installer.m", but when I try to run the code: [s, h] = sload('A01T.gdf') It didn't recognize the "sload". Someone know the reason?

You get 3 different error messages. This is not a smart idea of the programmer. Either the format is unknown, or there is a problem in the MEX function, or the file is not existing. It is trivial to check at least the last one:

exist(fullfile(cd, 'A01T.gdf'))

If the file does not exist, this is not a problem of the software. Simply provide the name of an existing file. It is much safer to include the folder name than to rely on the current folder what you expect it to be. Remember that any timer or GUI callback could change the current folder by cd. Therefore absolute file names are a good programming practice.
