Hello everyone, I got this error and I do not know how to solve. I used guidata(hObject, handles); but it solves the half of the error. Could you help me finding the problem in the following code please?

% HITUNG_LUAS_GUI MATLAB code for Hitung_Luas_GUI.fig
%      HITUNG_LUAS_GUI, by itself, creates a new HITUNG_LUAS_GUI or raises the existing
%      singleton*.
%
%      H = HITUNG_LUAS_GUI returns the handle to a new HITUNG_LUAS_GUI or the handle to
%      the existing singleton*.
%
%      HITUNG_LUAS_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in HITUNG_LUAS_GUI.M with the given input arguments.
%
%      HITUNG_LUAS_GUI('Property','Value',...) creates a new HITUNG_LUAS_GUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Hitung_Luas_GUI_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Hitung_Luas_GUI_OpeningFcn via varargin.

I think the file is corrupted but since you forgot to attach the dicom file it bombed on I can't be certain. Can you zip it up and attach it?

[Shynta Nanda]

can i have your number on whatsapp? because I don't understand how to zip

[Image Analyst]

No. In Windows File Explorer, just right click on the dicom file, and say Send to/Compressed (zipped) folder.

[Shynta Nanda]

this file

[Shynta Nanda]

please help me for the final exam

[Image Analyst]

You forgot to include the dicom image in that zip file. You only have 2 m-files. And what is the difference between the 2 m-files?

[Shynta Nanda]

sorry I forgot to include a picture of the dicom

CT Scan Image Processing do not use a guide, while Hitung_Luas_GUI using a guide and error

Sorry my English is bad

[Image Analyst]

Again you forgot to include the *.dcm dicom image. You included a JPEG photo. You cannot read jpeg photos with dicomread(). For *.jpg images, you use imread(), NOT dicomread(). Please include the DICOM version of the image - the one that you are actually trying to read.

[Shynta Nanda]

That's right, why don't I think about it

Thank you very much

can i learn more with you?

[Image Analyst]

Of course. See my File Exchange or ask here in the Answers forum.

[Shynta Nanda]

thank you :)

[Shynta Nanda]

by the way in my program guide why does image segmentation and binary images not appear? is there anything I forget about again?
