Error in abf2load (line 14) - cmd = sprintf('Abf2Tmp %s',fn); % Not enough input arguments %

I am trying to load an 'abf2' file using following code. But I am getting an error "not enough input arguments" in line 'cmd = sprintf('Abf2Tmp %s',fn)'. Can anyone help me with this?

function [data, metadata] = abf2load(fn) % function [data, metadata]=abf2load(fn) % this will load abf 2.0 files % in order for it to work you must have Abf2Tmp.exe and the dll in your % active directory.

    cmd = sprintf('Abf2Tmp %s',fn);
    system(cmd);
    tmpfname = sprintf('%s.txt',fn);
    data = load(tmpfname,'v1');

    metaDataFName = sprintf('%s-md.txt',fn);
    tabchar = sprintf('\t');
    fid = fopen (metaDataFName,'r');
    metadata = struct();  %start as an empty struct
    while 1
        %cycle through all the lines in the file and add all data to the
        %metadata struct
        tline = fgetl(fid);
        if ~ischar(tline), break, end
        valOffset = findstr(tline, tabchar);

        mdName = tline(1:valOffset-1);
        c = mdName(1);
        valOffset=[valOffset, size(tline,2)];
        for i=1:size(valOffset,2)-1
            mdVal = tline(valOffset(i)+1:valOffset(i+1));
            if (strcmp(c,'f') || strcmp(c,'n') || strcmp(c,'l') || strcmp(c,'u') || strcmp(c,'b') )
                val = str2num(mdVal);
            else
                val = {mdVal};
            end
            if (i > 1)
                metadata.(mdName) = [metadata.(mdName),val];
            else
                metadata.(mdName) = val;
            end
        end
    end

    fclose(fid);
    %clean up
    cmd = sprintf('del %s', tmpfname);  %command to delete the temp data file
    system(cmd);
    cmd = sprintf('del %s', metaDataFName); % command to delete the metadata file
    system(cmd);

The problem is the calling command, most likely. How do you call this function? You require

[data, metadata] = abf2load(Str)

with a matching value for the string variable "Str". How do you call this function?

[ishita agrawal]

This code belongs to abf2load package available online. I run the code to read the sample file provided in the package.

@ishita: While it does not matter, why you call the code, it matters how you do this. Do you provide the needed input argument or do you press the "Run" button of the compiler? In the last case there is no input in general and you would see the mentioned error message.

[ishita agrawal]

I was pressing "RUN" button. I got the point now. Thak you.
