Problem with opening an abf file using abfload

Hello,

I'm new to Matlab and Im trying to open an abf file using (https://fr.mathworks.com/matlabcentral/fileexchange/6190-abfload )

I've downloaded the code and called the function this way:

 fn="20505002.abf";
 [d,si]=abfload(fn,'start',0,'stop','e');

After RUN I get this Errors:

"Error using abfload (line 228)

invalid number format

Error in Try1 (line 5)

[d,si]=abfload(fn,'start',0,'stop','e');"

lines 217-228 in abfload is:

% tell me where the data start
blockSz=512;
switch nDataFormat
  case 0
    dataSz=2;  % bytes/point
    precision='int16';
  case 1
    dataSz=4;  % bytes/point
    precision='float32';
  otherwise
    fclose(fid);
    error('invalid number format');
end;

Can you tell me what I was doing wrong?

Thanks,

Neta.

Hi Neha,

Use disp(nDataFormat) before the switch case to see the output. As it is not 0 or 1, you are getting error. Check for corresponding DataFormat.
