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

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

>> help cd
cd Change current working directory.
cd directory-spec sets the current directory to the one specified.
cd .. moves to the directory above the current one.
cd, by itself, prints out the current directory.

Most of your callbacks still assume that the structure has been been completely created. Your code is not enabling and disabling buttons according to which elements of the structure are known to have been set, so a user can trigger a use of a field before the field is set. Remember, if the user can click the gui elements in an unexpected order then some user will do so.

In clothd_OpeningFcn add
handles.metricdata = struct('at', datetime(), 'K', 1, 'm', 0, 'Phc', 17, 'pm', 0.82, 'rt', datetime(), 'ST', datetime() );
before the "% Update handles structure"
Adjust these values to be sensible initial values for your purposes.
I recommend you also have another look at k_callback which currently has
K=str2double(get(hObject,'String'))
K=handles.metricdata.m/handles.metricdata.m
The first of those lines gets a number from a string, but the second of the lines overwrites that number with a value that is going to be either 1 (nearly all values) or nan (if the .m happened to be 0 or nan)

You never called st_Callback so handles.metricdata.ST never got assigned before you tried to use it.
Plus, you called your GUI "cd" which is a horrible idea because that is a built-in function and you should not name your own functions after built-in reserved functions.

Maybe later tonight. I'm off to explore Singapore now. Attach your .fig file, and your .m file with the paper clip icon.

In cd_OpeningFcn you need to assign a structure to handles.metricdata that has all of the fields that you are going to use . I say all of them because absolutely nothing in your code checks whether the various metricdata fields exist before going ahead and using them, so you need to assign usable defaults to every field before the user is permitted to interact with the GUI.
