Why do I get the errors "Missing operator, comma, or semicolon" and "eval(['dbstop in ' mfile ' at ' num2str(line_num)])"?

When I try to run a "stepthru analyze_series8 base" I get the following errors:

??? Error: File: C:\Documents and Settings\Administrator\Desktop\MRI_Brain_Scan\MRI Brain Scan\analyze_series8.m Line: 55 Column: 8
Missing operator, comma, or semicolon.

Error in ==> C:\Documents and Settings\Administrator\Desktop\MRI_Brain_Scan\MRI Brain Scan\StepThru.m
On line 32  ==>         eval(['dbstop in ' mfile ' at ' num2str(line_num)])

Here is the code of analyze_series8.m

%%Visualization
%----------------------------------------------------------------------

%explore image data using Image Viewer GUI tool
i = 30;  %middle slice
im = squeeze(D(:,:,i));
max_level = double(max(D(:))); 
imview(im,[0 max_level])

%custom display - image data
fig1 = figure;
max_level = double(max(D(:))); 
imshow(im,[0 max_level])
title('Coronal Slice #30')
set(fig1,'position',[601 58 392 314])
imview close all

The line 55 is the last one showed here "imview close all".

Here is the code from stepthru.m:

while ~feof(fid) %read 1 line at-a-time
  dummy=NoLeadingBlanks(fgetl(fid));
  line_num=line_num+1;
  if length(dummy)>0 %nonempty line
    if dummy(1)=='%' & line_num>1 %comment line but not line1
      if strfind(lower(dummy),'nobkpt') %no breakpoint this line
        eval(['dbclear in ' mfile ' at ' num2str(line_num)])
      else
        eval(['dbstop in ' mfile ' at ' num2str(line_num)])
      end
    end
  end
end %file empty
fclose(fid);

The line 32 is the following: "eval(['dbstop in ' mfile ' at ' num2str(line_num)])".

Please help me here!!

If you look at the submission's page on the File Exchange, the author says this:

"Note for users who get stuck by the IMVIEW error. That function was replaced by IMTOOL (years ago). In analyze_series8.m just replace all occurrences of "imview" with "imtool" (and save)."

I think this may fix the error you're getting.
