(1) Use fullfile() to construct the full path; (2) instead of cd'ing to namedir and using pwd(), use pathname as the directory component in fullfile() (3) filename will be a cell array, so dereference it; (4) filename() will probably be a column array instead of a row array, so instead of using the second component of size(), use the first. Or better yet, use length() and then don't worry about whether it is row or column

for x = 1 : length(filename)
  img = dicomread( fullfile(pathname, filename{x}) );
end

  end

ERROR message:

Cell contents reference from a non-cell
array object.

[vaishali]

 filename is a cell array how to dereference it;

[vaishali]

if more than one image selected Error message: Undefined function 'eq' for input arguments of type 'cell'.

Error in fullfile (line 37) if (f(end)==fs) && (part(1)==fs),

[Walter Roberson]

After the if/else/end, but before for loop, add

filename = cellstr(filename);

That will deal with the case where you only select a single file.

[vaishali]

yes it works with single file. but i have to select multiple files and process them & store results in excel worksheet.Is it possible to program for multiple selection?

[vaishali]

For multiple selection.ERROR message: Undefined function 'eq' for input arguments of type 'cell'.

Error in fullfile (line 37) if (f(end)==fs) && (part(1)==fs),

[Walter Roberson]

The code should work. Put in a breakpoint at the "img =" assignment and run your code and select multiple. When it stops, display

class(filename), size(filename)

if filename shows up as cell, then

class(filename{1})
