MATLAB: Struct contents reference from a non-struct array object.

imagesstruct

folder = 'C:\Echo Images\Stelios\FDB';
file_temp = sprintf('%s\\*.bmp', folder);
filearray = dir(file_temp);
s = max(size(filearray));
for i=1: 1: s
    [p, f] = fileparts(file_temp(i).name);
    imgname=strcat(folder,'\\',filearray(i).name);
    I = imread(imgname);
    dicomwrite(I, [imgname '.dcm']);
end
I get the error at     [p, f] = fileparts(file_temp(i).name); line. PLease help!!

You want the output of dir, not the one of sprintf:
file_temp = sprintf('%s\\*.bmp', folder);
filearray = dir(file_temp);
for i = 1:s
  [p, f] = fileparts(filearray(i).name);  % file_temp => filearray
By the way:
  • Please format your code in the forum using the "{} Code" button. It is a good idea to post readable code.
  • An easier method to create the file pattern:
% file_temp = sprintf('%s\\*.bmp', folder)
file_temp = fullfile(folder, '*.bmp');
  • The field .name contains the file name only, so there is no need to split it by fileparts.
p = filearray(i).folder;
f = filearray(i).name;
But you not need p or f at all.
  • Use fullfile instead of strcat:
imgname = fullfile(folder, filearray(i).name)
