I'm doing some reading and manipulation of a very large text file and this takes alot of time. Is there a way to have a status bar of how much time is left to complete a job once you hit the run button?
MATLAB: Job timer

No, I don't think so. Waitbar needs a fraction of the total processing time, and you cannot implant this function into a build in function.
Your timer function @axes1.handles is completly invalid, it's no function.
Also the way you start and stop the timer isn't correct, should give you too many errors.
Here's a GUI that I made with GUIDE, the fig file is just one axes and one pushbutton, the m file code is:
function varargout = rottest(varargin)% ROTTEST M-file for rottest.fig
% ROTTEST, by itself, creates a new ROTTEST or raises the existing
% singleton*.
%
% H = ROTTEST returns the handle to a new ROTTEST or the handle to
% the existing singleton*.
%% ROTTEST('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in ROTTEST.M with the given input arguments.
%% ROTTEST('Property','Value',...) creates a new ROTTEST or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before rottest_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to rottest_OpeningFcn via varargin.
%% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
