What should I put in Filen to place to Function?

function [ tag, out, out2, out3, lMin, lMax, res] = loadBImage(filen)
%   Load image from Cono-Point Acquisition
tic
fname = [filen '.dist']

%load float-distances from dist file
fid=fopen(fname)

fclose(fid);
size(vals)

%load parameters from header file
filename = [filen '.hdr']
fid=fopen(filename);
C=textscan(fid,'%s%s%s')
fclose(fid);

off=str2double(strrep(C{2}(11),',','.'));                   %get offset
dir=char(C{2}(12))                                        %get scansion direction
lMin=str2double(C{2}(18))                                  %get Min-Max WorkingRange
lMax=str2double(C{2}(19))
res=str2double(strrep(C{2}(8),',','.'))                   %get res
y=str2double(strrep(C{2}(9),',','.')); y=((y-2*off)/res)+1; strrep(y,',','.')    %get Xres
x=str2double(strrep(C{2}(10),',','.')); x=x/res+1; strrep(y,',','.')             %get Yres         

%load SNR file and get %

toc

end

I have 4 file .tag , .snr . hdr .dist ....

[Stephen23]

The input filen should be the filename without any file extension.

All of the four files must have the same name (only the file extensions are different).

@Berto Rossi, please use comment on this answer rather than starting a new answer

Berto Rossi's comment moved here from answer:

But when i try to put the file name in the file, , this is the error

   function [ tag, out, out2, out3, lMin, lMax, res] = loadBImage(Argento_3_R)
